libext2fs: set BLOCK_UNINIT for non-last blockgroups if all blocks are free

Set BLOCK_UNINIT in any group whose blocks are all unused, so long as
it isn't the last group.  This helps us speed up future e2fsck runs
and mounts because we don't need to read or checksum block bitmaps for
these groups.
