This tmpfiles.d wants to write to sysfs, which is read-only in containers,
so systemd-tmpfiles --create fails in TEST-22-TMPFILES when ran in nspawn
if the selinux policy package is instealled. Mask it, as it's not our
config file, we don't need it in the test.
Having these named differently than the test itself mostly creates
unecessary confusion and makes writing logic against the tests harder
so let's rename the testsuite-xx units and scripts to just use the
test name itself.
