This reintroduces 4fa4f90ccd (submodule: unset core.worktree if no working
tree is present, 2018-06-12), which was reverted as part of f178c13fda
(Revert "Merge branch 'sb/submodule-core-worktree'", 2018-09-07).
4fa4f90ccd was reverted as its followup commit was faulty, but without
the accompanying change of the followup, we'd have an incomplete workflow
of setting `core.worktree` again, when it is needed such as checking out
a revision that contains a submodule.
So re-introduce that commit as-is, focusing on fixing up the followup
