Now that bisection does not require checkout, it can work
on bare repositories too.
In this case, we default the checkout mode to --no-checkout,
thereby forcing the creation of BISECT_HEAD on either a manual
or automatic start.
The require_work_tree check in git-bisect.sh and the NEED_WORK_TREE
check in git.c are relaxed.
