linux-v4l2: Add eventfd to signal udev on shutdown ...
Currently we use signals based on os_event's but the udev code blocks in
a 1s select (now poll) that cannot be signalled without an FD. This adds
an extra eventfd which will be signalled along with the os_event to
trigger the poll.
Also switches from select to poll to avoid issues with large fd values.
