[Bug 2067927] [NEW] systemd ships nice.conf override for wrong service

[Nick Rosbrook]

Public bug reported:

[Impact]

Prior to Noble (since Bionic or so), we shipped systemd-journald.service
with Nice=-1 due to bug 1696970. In Noble, we intended to do this with a
drop-in config instead of an out-of-tree patch [1]. But, this drop-in
was mistakenly shipped for systemd-logind.service, instead of systemd-
journald.service. This means the mitigation for bug 1696970 is no longer
in place on Noble, and users could potentially see regressions.

[Test]

Check that systemd-journald.service has Nice=-1 configured (and that
systemd-logind.service does not):

$ systemctl show -p Nice systemd-journald.service 
$ systemctl show -p Nice systemd-logind.service

[Where problems could occur]

Clearly, we should be careful that the drop-in is shipped for the
correct service, otherwise we may apply the setting to the wrong unit.

[Other information]

I have not actually seen any regressions reported about this, but as we
intended to keep the Nice=-1 setting for systemd-journald.service, we
should restore it.
