Subject: dgit: Separate out build_check_quilt_splitbrain

The only effect of this is to move the tag format check from before
the main work of build_maybe_quilt_fixup to later, and to not check it
at all for `dgit quilt-fixup'.

We don't really care about this any more; this tag format stuff is
obsolete and we will delete it at some point...
