Added support for PARTUUID=

Browse Source 
The Linux kernel expects partitions that are identified by uuid,
to have the the uuid prefixed by "PARTUUID=" and an optional suffix
of "PARTRNOFF=%d".

The change adds additional pattern matching for these strings.

This will also let get rid of custom uuid processing in dm-verity,
dm-bootcache and dm-verity-chromeos.
