e2fsprogs: Remove all mention of anything associated with uuids
--disable-libuuid is added to the configure command line. This has
the effect of disabling the compilation of uuidgen and libuuid.so.
These two are specified as making up their own packages, which turn
out to be empty, and thus aren't created in the first place. The
error which manifests itself is at the final creation of the rootfs
when the global package depends on the e2fsprogs-uuidgen and libuuid,
which turn out not to exist, because they weren't created.
