Add `services.nginx.lua.{enable,extraPackages}` to enable OpenResty's
lua-nginx-module on a stock nginx. When enabled it adds the module,
includes lua-resty-core, and wires up lua_package_path /
lua_package_cpath (and lua_ssl_trusted_certificate) from a
luajit_openresty package set built from extraPackages.
When the configured package already bundles Lua (openresty), the module
and bundled libraries are not re-added; only the search path is set up so
its own lualib stays in use.
Migrate the openresty-lua test to the new option and add an nginx-lua
test covering the stock-nginx path.

After final improvements to the official formatter implementation,
this commit now performs the first treewide reformat of Nix files using it.
This is part of the implementation of RFC 166.
Only "inactive" files are reformatted, meaning only files that
aren't being touched by any PR with activity in the past 2 months.
This is to avoid conflicts for PRs that might soon be merged.
Later we can do a full treewide reformat to get the rest,
which should not cause as many conflicts.
A CI check has already been running for some time to ensure that new and
already-formatted files are formatted, so the files being reformatted here
should also stay formatted.

There's no point for the intermediate `getPath` function calling
`getLuaPath` with the "lua" argument.
There's also no other nginx test this copies code from.
We always call `getLuaPath` with "lua", so constant-propagate it in.
Also, camel-case `lualibs` to `luaLibs.`
nginx lua needs resty
the enableSandbox option of nginx was removed in 535896671b
the test fails with
