[OE-core] [PATCH 1/2] wic: When using --use-uuid make sure that we update the fstab with PARTUUID

[Tom Rini]

When we have been told to use the UUID we should also update the fstab
to make use of PARTUUID instead of hard-coding the device in question.
This will make the resulting image much more portable.
