tests: merge test-tmpfiles.c into test-tmpfile-util.c

The former was added in 65b3903ff576488eaabb51d3c4fbf9c73d867d7c,
but the name is confusing: the test has nothing to do with systemd-tmpfiles.
It had one function that mostly tested functions from tmpfile-util.c, so
just move it into the latter.
