mv: Fix spurious warning when moving a file in presence of submodules

Browse Source 
In commit 0656781fa "git mv" learned to update the submodule path in the
.gitmodules file when moving a submodule in the work tree. But since that
commit update_path_in_gitmodules() gets called no matter if we moved a
submodule or a regular file, which is wrong and leads to a bogus warning
when moving a regular file in a repo containing a .gitmodules file:

    warning: Could not find section in .gitmodules where path=<filename>

Fix that by only calling update_path_in_gitmodules() when moving a
submodule. To achieve that, we introduce the special SUBMODULE_WITH_GITDIR
define to distinguish the cases where we also have to connect work tree
and git directory from those where we only need to update the .gitmodules
setting.

A test for submodules using a .git directory together with a .gitmodules
file has been added to t7001. Even though newer git versions will always
use a gitfile when cloning submodules, repositories cloned with older git
versions will still use this layout.
