submodule.c: use get_git_dir() instead of get_git_common_dir()
Ever since df56607dff (git-common-dir: make "modules/"
per-working-directory directory, 2014-11-30), submodules in linked worktrees
are cloned to $GIT_DIR/modules, i.e. $GIT_COMMON_DIR/worktrees/<name>/modules.
However, this convention was not followed when the worktree updater commands
checkout, reset and read-tree learned to recurse into submodules. Specifically,
submodule.c::submodule_move_head, introduced in 6e3c1595c6 (update submodules:
add submodule_move_head, 2017-03-14) and submodule.c::submodule_unset_core_worktree,
(re)introduced in 898c2e65b7 (submodule: unset core.worktree if no working tree
is present, 2018-12-14) use get_git_common_dir() instead of get_git_dir()
to get the path of the submodule repository.
This means that, for example, 'git checkout --recurse-submodules <branch>'
in a linked worktree will correctly checkout <branch>, detach the submodule's HEAD
at the commit recorded in <branch> and update the submodule working tree, but the
submodule HEAD that will be moved is the one in $GIT_COMMON_DIR/modules/<name>/,
i.e. the submodule repository of the main superproject working tree.
It will also rewrite the gitfile in the submodule working tree of the linked worktree
to point to $GIT_COMMON_DIR/modules/<name>/.
This leads to an incorrect (and confusing!) state in the submodule working tree
of the main superproject worktree.
Additionally, if switching to a commit where the submodule is not present,
submodule_unset_core_worktree will be called and will incorrectly remove
'core.wortree' from the config file of the submodule in the main superproject worktree,
$GIT_COMMON_DIR/modules/<name>/config.
Fix this by constructing the path to the submodule repository using get_git_dir()
in both submodule_move_head and submodule_unset_core_worktree.
