Remove RFC-4122 from e2fsprogs distribution

Remove RFC-4122 from e2fsprogs distribution

Documentation about UUID's is available in enough places, and it's
awkward to deal with debian-legal's insanities.  So I'm caving in the
"more-lunatic-than-RMS" wing of Debian by removing RFC-4122 so we don't
have do the dfsg tarball.   Also remove the rule that only tried to
install RFC-4122 on Ubuntu, since Ubuntu seems to want to fetch
e2fsprogs exclusively from Debian.
