[Bug 1548120] Re: [xenial][initramfs-tools] support uppercase and lowercase uuids

[hakuna_matata]

The fix doesn't work for UUIDs of a Windows file system. blkid uses
always UUIDs in upper case for these file systems. So it fails because
the fix converts all UUIDs in lower case.

IMHO short UUIDs (length <= 16) should be always converted in upper case
because short UUIDs are only UUIDs of a Windows file systems.

It can affect also systems without Windows because the EFI partition has
a Windows file system (vfat).

In my case it fails booting into a loopback device(ext4) on a Windows
file system (ntfs).

Please fix your patch. Thanks.
