[PATCH v2 6/6] maintenance: update tests for systemd scheduler

[Max Gautier <mg@max.gautier.name>]

The systemd units are now in the source tree, rather than produced when
running git maitenance start. There is no need anymore to couple
validating the units and testing `git maintenance start`.

Adjust the test to verify the new `systemctl` command used, discard
checks for presence/absence of unit files in $XDG_CONFIG_HOME.

Validate the systemd units in the source tree, with one test per unit to
have more distinct failures.

Notes:
    I encountered the same issue that
    cover.1697319294.git.code@khaugsbakk.name tried to solve; I was
    expecting multiples tests to be independent while they weren't (in
    particular the MacOS ones).
