Silvan Mosberger 4f0dadbf38 treewide: format all inactive Nix files
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.

When enabled, instructs udisks2 to mount removable drives under `/media/` directory, instead of the
default, ACL-controlled `/run/media/$USER/`. Since `/media/` is not mounted as tmpfs by default, it
requires cleanup to get rid of stale mountpoints; enabling this option will take care of this at boot.
