tests/libqtest.c: Delete possible stale unix sockets
Occasionally if a test crashes or is interrupted by the user at the wrong moment it could leave behind a stale UNIX socket in /tmp/. This will then cause a subsequent test run to fail spuriously with tests/libqtest.c:70:init_socket: assertion failed (ret != -1): (-1 != -1) if it happens to reuse the same PID. Defend against this by deleting any stray stale socket before trying to open the new ones for this test.
