Fix growpart for some cases when booted with root=PARTUUID.
Growing the root partition would fail in either of two cases:
a.) if the device /dev/root existed
b.) the kernel command line had upper case letters in PARTUUID=<value>
the kernel will accept upper case partuuid, but udev creates
links with lower case. In that scenario, we need to adjust to
a /dev/disk/by-<partuuid|uuid> with lower case.
The fix here addresses that, and also fixes uuid similarly for the
lowercase issue.
