meta-crownbay: apply init-live.sh coldplug udev trigger patch here instead

At the moment, we can't spin a new laverne release, so we need to
add it to the crownbay layer instead.

+Subject: [PATCH 1/2] init-live.sh: add 'coldplug' udev trigger
+
+Fixes [BUGID #693]
+
+The init-live.sh script starts udevd in init-live.sh:early_setup(),
+but doesn't account for the possibility that the root device may have
+already been registered by the kernel before udevd starts up.
+
+If the device is detected after udevd starts up, everything's fine -
+udevd gets the 'add' uevent for the device, the root image shows up at
+e.g. /media/sda/rootfs.img, and the boot continues.
+
+If however the device is detected before udevd starts up, udevd misses
+the 'add' uevent and the root image never shows up, causing it to stay
+in the 'waiting for removable media' loop forever.
+
+The 'udevadm trigger' command is meant to be used to avoid this
+situation, but init-live.sh doesn't use it.  Furthermore, since the
+default was changed in udev 152 from 'add' to 'change', the command
+needs to explicity name 'add' as the action.
