nixos/tests: Remove tests.boot.boot* prefixes

As @bobvanderlinden suggests in #13585:

"Looks like that cleans things up quite a bit! Just one aesthetics note,
the boot tests could now be renamed from boot.bootBiosCdrom to
boot.biosCdrom in nixos/tests/boot.nix:L33.

That makes them more consistent with the other tests."

+# Introduction
+
+The Nix Packages collection (Nixpkgs) is a set of over 30,000 packages for the
+[Nix package manager](http://nixos.org/nix/), released under a [permissive MIT/X11 license](https://github.com/NixOS/nixpkgs/blob/master/COPYING).
+Packages are available for several architectures, and can be used with the Nix package manager
+on most GNU/Linux distributions as well as NixOS.
+
+This manual describes how to write packages for the Nix Packages collection
+(Nixpkgs). Thus it’s for packagers and developers who want to add packages to
+Nixpkgs. If you like to learn more about the Nix package manager and the Nix
+expression language, then you are kindly referred to the [Nix manual](http://nixos.org/nix/manual/).
+
+## Overview of Nixpkgs
+
+Nix expressions describe how to build packages from source and are collected in
+the [nixpkgs repository](https://github.com/NixOS/nixpkgs). Also included in the
+collection are Nix expressions for [NixOS modules](http://nixos.org/nixos/manual/index.html#sec-writing-modules). With
+these expressions the Nix package manager can build binary packages.
+
+Packages, including the Nix packages collection, are distributed through
+[channels](http://nixos.org/nix/manual/#sec-channels). The collection is
+distributed for users of Nix on non-NixOS distributions through the channel
+`nixpkgs`. Users of NixOS generally use one of the `nixos-*` channels, e.g.
+`nixos-15.09`, which includes all packages and modules for the stable NixOS
+15.09. The channels of the stable NixOS releases are generally only given
+security updates. More up to date packages and modules are available via the
+`nixos-unstable` channel.
+
+Both `nixos-unstable` and `nixpkgs` follow the `master` branch of the Nixpkgs
+repository, although both do lag the `master` branch by generally [a couple of days](http://howoldis.herokuapp.com/). Updates to a channel are distributed as
+soon as all tests for that channel pass, e.g. [this table](http://hydra.nixos.org/job/nixpkgs/trunk/unstable#tabs-constituents)
+shows the status of tests for the `nixpkgs` channel.
+
+The tests are conducted by a cluster called [Hydra](http://nixos.org/hydra/),
+which also builds binary packages from the Nix expressions in Nixpkgs. As soon
+as a channel is updated, the binaries are made available via a [binary cache](https://cache.nixos.org). Until the channel updates, binaries that have
+already been built, are available via [Hydra's binary cache](https://hydra.nixos.org).
+
+The current Nix expressions of the channels are available in the
+[`nixpkgs-channels`](https://github.com/NixOS/nixpkgs-channels) repository,
+which has branches corresponding to the available channels. There is also the
+Nixpkgs Monitor which keeps track of updates and security vulnerabilities.

+example, <varname>qt5Libs</varname> always provides libraries built

+libraries built with Qt 5.5, and so on. To avoid version conflicts, no

+<para>Application packages do not need to be built with every Qt
+version. To ensure consistency between the package's dependencies,
+call the package with <literal>qt5Libs.callPackage</literal> instead
+of the usual <literal>callPackage</literal>. An older version may be
+selected in case of incompatibility. For example, to build with Qt
+5.5, call the package with
+<literal>qt55Libs.callPackage</literal>.</para>
