This matches the default behavior on Linux. If D-Bus defaults to launchd
activation, all packages or tests using `dbus-run-session` will fail due
the launch agent not being installed and available.
Some binaries have incorrect install names. They should be the absolute
path, but they have `@rpath` instead. This something that Meson should
handle automatically, but it’s not happening for these binaries.

The dbus meson.build requires both libaudit and libcap-ng when libaudit
support is enabled:
have_libaudit = libaudit_ok and cap_ng_ok
While the audit package itself depends on libcap_ng, that dependency
doesn't make libcap_ng available in dbus's build environment. Adding it
explicitly fixes the build failure:
Library cap-ng found: NO
meson.build:556:8: ERROR: Problem encountered: libaudit support
requested but not found
- Meson tries to detect that `launchctl` is present. Lie to it because
it will always be present on a Darwin host platform; and
- Install the launch agent plist to `$out` instead of an impure path.
Without this patch, the vendored implementation of `getgrouplist` is
always used regardless of what is detected and set in `config.h`. The
function signature provided conflicts with the one in the SDK on Darwin.
Moving the condition to make it actually conditional fixes Darwin.
These will be enabled by default due `-Dauto_features=enabled` being set
in Nixpkgs. However, not all of those features are available on every
platform supported by D-Bus, so set them conditionally.
this creates some eval errors that will be fixed in the next commit

This includes:
- Switch from Autotools to Meson
- Since Meson does not support separate `installFlags`, we would either need to use `DESTDIR`, or patch the build system. I chose the latter since we want to keep the `$out` as close to FHS as possible to avoid confusion, and moving a subset of content of `$out/etc` back to `$out/share` would be annoying.
- `libaudit` started to require `libcap-ng`.
- `xmlto` was replaced by `xsltproc`.
- Extra docs builds, disabled for now due to dependency requirements.
In the package definition:
- Use `finalAttrs`.
- Use `--replace-fail` with `substitute`.
- Make `getgrouplist` unconditional.
The propagation was introduced in 7d9607f151 without any context.
But the library is only used by dbus-daemon so it does not make sense to propagate it.
