[eudev] [PATCH] libudev-monitor.c: fail to monitor udev if udev is not started

[Marcus Folkesson <marcus.folkesson@gmail.com>]

We makes two controls if we consider udev is started;
	access(UDEV_ROOT_RUN "/udev/control", F_OK) < 0
and
	!udev_has_devtmpfs(udev))

If one(not both) of these statements fails, we consider that udev is not
running.
