wic: fix generation of partition UUID
Partition UUID for msdos partitioning is based on a 4 bytes long
system identifier. Wic uses random number to generate system
identifier. For the numbers starting with 0 partition uuid is
shorter, which makes wic images non-bootable as kernel expects
8 charactest in PARTUUID parameter.
Padded system identifier with '0' when generating partition UUID
to make it always 8 characters long. This should fix the boot
issue.
