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.

Systemd units with `PrivateUsers` set get their capabilities within the user namespace only [1].
As a result they do cannot bind to privileged ports even though they *appear* like they should be able to.
The units in this commit [2] set `PrivateUsers` unconditionally so binding to privileged ports is currently impossible.
Granting them CAP_NET_BIND_SERVICE is useless and misleading any reader of those modules.
Technically, this commit also hardens these modules ever so slightly.
(There are corner cases where this could make sense (e.g. across units, using `JoinsNamspaceOf`) but this is arcane enough to not to be present in nixpkgs.)
[1]: systemd.exec(5): PrivateUsers
[2]: found using `rg -e 'PrivateUsers.?=\s+[^f][^a]' -l | xargs rg -e '\bCAP_' -l`
