revert: stop creating and removing sequencer-old directory 

Now that "git reset" no longer implicitly removes .git/sequencer that
the operator may or may not have wanted to keep, the logic to write a
backup copy of .git/sequencer and remove it when stale is not needed
any more.  Simplify the sequencer API and repository layout by
dropping it.
