third_party/linux: expose PARTUUID through uevent

The kernel was patched to expose partition UUIDs.

This was inspired by a change [1] that didn't make it into mainline.
The patch is meant for internal use and would need to be adapted for
mainlining due to recent changes in the part of codebase involved.
