[PATCH v2 1/2] clean: avoid looking for nested repositories when unnecessary

[Patrick Marlier <patrick.marlier@gmail.com>]

With `git clean --ff` we will be deleting nested untracked repositories,
so there is no need to differentiate them from other untracked files.
Use the DIR_NO_GITLINKS flag in dir.flags to signify this and avoid the
is_nonbare_repository_dir() checks.
