run-tests: fix TESTDIR if testdescs are absolute paths
Commit
a18eef03d879 made TESTDIR be the location of the arguments that were
passed to run-tests.py instead of just PWD. It assumed that these tests were
specified using relative paths, so if pwd was /tmp/foo, and the first argument
was /tmp/baz, it would set TESTDIR to /tmp/foo//tmp/baz.
