[git commit] md5/shaXsum: accept uppercase hex strings

[Denys Vlasenko]

commit: https://git.busybox.net/busybox/commit/?id=a3c50683069c797ef328f6e32c6282d5d3243c98
branch: https://git.busybox.net/busybox/commit/?id=refs/heads/master

The coreutils versions of md5sum and the like accept uppercase hex
strings from checksum files specified with the '-c' option.

Use a case-insensitive comparison so BusyBox does the same.
