t7900: fix host-dependent behaviour when testing git-maintenance(1)

We have recently added a new test to t7900 that exercises whether git-maintenance(1) fails as expected when the "schedule.lock" file exists. The test depends on whether or not the host has the required executables present to schedule maintenance tasks in the first place, like systemd or launchctl -- if not, the test fails with an unrelated error before even checking for the lock file. This fails for example in our CI systems, where macOS images do not have launchctl available. Fix this issue by creating a stub systemctl(1) binary and using the systemd scheduler.
