tests: Move perl tests to tests/, make them callable from top-level Makefile

Use "make test" or "make test-verbose" to run.
Note that "make test" seems to be more common than "make tests", hence the
change.

Also, use a new clean directory directory as a working area for each run
Created using mkdtemp and deleted in cleanup()
