Otherwise, if a test in a spurious state, it consumes quite long time.
Let's fail earlier in such case.
This also drops an unnecessary calls of 'udevadm settle' in
testcase_nvme_basic() of TEST-64-UDEV-STORAGE.
Recently, for slow test environments, journalctl --sync was added to the
loop in the timeout. However, journalctl --sync may be slow in such systems,
and timeout easily triggered during syncing.
Hopefully, reading journal with --follow and grep the output with an expected
line should be efficient.
Hopefully fixes#32712.
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.
