scmutil: try-delete `.hg/store/requires` if store requirements are empty

When downgrading from a shared-safe repository to non-shared-safe repository, we
end up in a case where we had requirements stored in `.hg/store/requires` but no
longer want them there.

Let's explicitly try delete the `.hg/store/requires` file if store requirements
are empty.
