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.

The reason for this is that `sudo(8)` writes the lecture to the
tty[1] and only as a fallback to stdout[2]. This means that the
`base64 --wrap 0` executed by `machine.execute()` doesn't affect the
text written to the terminal, however the lecture is part of the string
that's read from the VM via `shell.recv()`.
I confirmed the problem in an interactive test session[3]:
>>> command = "sudo -u test5 sudo -n -u root true"
>>> out_command = f"( set -euo pipefail; {command} ) | (base64 --wrap 0; echo)\n"
>>> machine.shell.send(out_command.encode())
84
>>> machine # [ 99.015512] sudo[877]: root : TTY=hvc0 ; PWD=/tmp ; USER=test5 ; COMMAND=/run/wrappers/bin/sudo -n -u root true
machine # [ 99.019373] sudo[877]: pam_unix(sudo:session): session opened for user test5(uid=1005) by (uid=0)
machine # [ 99.038692] sudo[879]: pam_unix(sudo:auth): conversation failed
machine # sudo: a password is required
machine # [ 99.041860] sudo[879]: pam_unix(sudo:auth): auth could not identify password for [test5]
machine # [ 99.046901] sudo[877]: pam_unix(sudo:session): session closed for user test5
>>>
>>> x=machine._next_newline_closed_block_from_shell()
>>> print(x)

We trust you have received the usual lecture from the local System
Administrator. It usually boils down to these three things:
<newline>
#1) Respect the privacy of others.
#2) Think before you type.
#3) With great power comes great responsibility.
<newline>
<newline>
<newline>

Since the lecture isn't strictly necessary to confirm that
`security.sudo` works as expected, I decided to disable lecturing
inside the test, however we may want to fix the underlying problem in
the test-driver at some point.

[3] I replaced each empty line with `<newline>` to make sure these
aren't swallowed by git.
One of the subtests in the sudo NixOS test suite was broken: instead of
running the sudo invocation as user 'test2', it was running it as root.
Since root doesn't require a password to use sudo, this was causing
random "broken pipe" errors when trying to pass it a password via stdin.
