Video4Linux2 plugins can udev for device probing and monitor.
This greatly improves load time and monitoring performance.
It also enables hotplug monitoring for cameras.

v3:
* Apply the dependency only if V4L2 plugins are enabled
v2:
* Enable/disable v4l2-gudev explicitly

Here, I've added a blurb explaining why we do not propagate the
dependencies from libgudev eventhough we select it.
I am always a bit conflicted that we don't do that explicitly, even if
superfluous.
But heck, the libglib2 world is not ready to drop the existing
dependencies (MMU, wchar, and threads) anytime soon, so this ought
to be enough for everybody (famous last words).

Applied to master, thanks.
