Brandon Philips f17c5fa573 95rootfs-block: fix PARTUUID parsing
In the kernel comments PARTUUID is shown using uppercase A-F:
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/init/do_mounts.c?id=HEAD#n183

However, dracut tries to use the value of PARTUUID directly in
/dev/disks/by-partuuid/ which expects the hex to be lowercase. This will
cause root to never be found, oops!

Fix dracut so it can, like the Kernel, accept either casing.

Untested but I added a hack on my local system that was similar.
