[PATCH] host/rootfs: delay Weston until udevadm settle

[Alyssa Ross <hi@alyssa.is>]

We might not get a card0; rather a card1.  There's no easy way to wait
for multiple devices with udev, so instead we just wait for all boot
events to have been processed.  Later, we will get COSMIC to allow
being started with no cards available.  For now, this is fine.

(If somebody boots with no GPU, and then hotplugs one, we allow Weston
to restart in a loop until that happens.  That should be pretty uncommon.)
