baseimager: export partition device node

Also export the device node name for each partition. This will be helpful when
we start generating fstab entries in the installer framework scripts.

In MIC environment, the device node name is easily constructed from the disk
name.  The disk name compes from the KS file from the --ondisk option of the
'part' command. And --ondisk is a mandatory argument.

In other installer environments, the disk names may be very different.
