set stages for `destroyed-symlinks`

The 'destroyed-symlinks' hook runs upon 'commit-msg' hook,
however when used in 'git submodules', repository scope breaks

> pre_commit_hooks.util.CalledProcessError: (('git', 'status',
> '--porcelain=v2', '-z', '--', '.../COMMIT_EDITMSG'), 0, 128, '',
> b"fatal: .../COMMIT_EDITMSG: '...' is outside repository at '...'\n")
