This will remove all state directories related to CUPS on startup, which
is particularly useful for guaranteeing that printer discovery works
more reliably on some networks, since CUPS will no longer be able to
store state that effects the next run of the service, such as old
printer names and mDNS information.

It failed since pipefail (b7749c7, PR #125683), due to `systemctl status`
not exiting with code=0 for inactive units (apparently).
That command is meant for humans anyway.
Use systemd to create the directory for UNIX socket. Also use localhost instead
of 127.0.0.1 as is done in default cupsd.conf so that IPv6 is enabled when
available.
Two fixes:
Not really sure why removing `--fail` from the curl calls is necessary,
but with that option, curl erronously reports 404 (which it shouldn't
per my interactive vm testing).
Fix paths to example files used for the printing test
Toghether, these changes allow the test to run to completion on my machine.
It looks like now queue is not immediately cleared from cancelled jobs.
Instead, files like "c00001" are left alongside "d00001-001", and
cleanup happens at some later point of time. Also, all new jobs are
assigned consecutive numbers now (00002, 00003 etc.). So when
original d00001 file is finally cleaned, it breaks the test. Fixed
by checking for any "d*" file inside the queue and cleaning it by
ourselves to ensure that each job works correctly.
It seems like there's an upstream bug in the "lpstat" command. We need
to specify the server's port.

You can now run a test in the nixos/tests directory directly using
nix-build, e.g.
$ nix-build '<nixos/tests/login.nix>' -A test
This gets rid of having to add the test to nixos/tests/default.nix.
(Of course, you still need to add it to nixos/release.nix if you want
Hydra to run the test.)
