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.

This is very useful in conjunction with meta.pkgConfigModules, as the
new tester can use the list provided by this meta attribute as a default
value for moduleNames, making its usage in passthru.tests very
convenient.
For backwards compatibility, a shim under the old name is maintained
with a warning.
The command at the top of this file fails to evaluate:
```
$ nix-build -A tests.pkg-config.defaultPkgConfigPackages
in job ‘nixpkgs.tests.pkg-config.defaultPkgConfigPackages.tests-combined.x86_64-linux’:
error: pkg-config module `recurseForDerivations` is not defined to be a derivation. Please check the attribute value for `recurseForDerivations` in `pkgs/top-level/pkg-config-packages.nix` in Nixpkgs.
```
This is also causing eval errors on Hydra:
https://hydra.nixos.org/jobset/nixos/pr-209870-gcc-external-bootstrap#tabs-errors
Let's filter out `recurseForDerivations=true` from the attrset,
since it exists mainly as a flag to signal special handling when
recursing.
