udev: ignore devices set to be ignore elsewhere

Browse Source 
There are already some other rules to ignore not interesting devices.
This includes device-mapper assembled in initramfs manually. 'dmroot'
isn't properly detected as mounted because /dev/mapper/dmroot isn't a
symlink to /dev/dm-0 and /proc/mounts contains the former name, while
udev event the later.

Fixes QubesOS/qubes-issues#1586
