[PATCH stalld 35/36] tests/functional: Fix invalid pidfile test in test_pidfile

[Wander Lairson Costa <wander@redhat.com>]

The test created a directory with no write permission and expected
stalld to fail writing the pidfile. Since the tests run as root,
the permission restriction has no effect and stalld succeeds. Use
a non-existent parent directory instead so fopen() fails regardless
of privileges.
