The sequencer currently passes GIT_DIR, but not GIT_WORK_TREE, to exec
commands.  In that configuration, we assume that whatever directory
we're in is the top level of the work tree, and git rev-parse
--show-toplevel responds accordingly.  However, when we're in a
subdirectory, that isn't correct: we respond with the subdirectory as
the top level, resulting in unexpected behavior.

Ensure that we pass GIT_WORK_TREE as well as GIT_DIR so that git
operations within subdirectories work correctly.

Note that we are guaranteed to have a work tree in this case: the
relevant sequencer functions are called only from revert, cherry-pick,
and rebase--helper; all of these commands require a working tree.
