Subject: [PATCH] udevadm-settle: fixed return code for empty queue

If the udev queue is empty and "/run/udev/queue" does not exist,
"udevadm settle" would return with EXIT_FAILURE, because the inotify on
"/run/udev/queue" would fail with ENOENT.

This patch lets "udevadm settle" exit with EXIT_SUCCESS in this case.
