Let's remove the unneeded NotifyAccess=all and start the socket
and service in the test itself instead of via the service unit. This
makes the test unit identical to the other test units which will allow
us to autogenerate it in a later commit.
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.
