Title: #5343: autofs: distinguish between empty cache and offline state

"""
Even though autofs uses nsswitch.conf for database order, it does not use its logic (the autofs api is not part of glibc). But the [code](https://git.kernel.org/pub/scm/linux/storage/autofs/autofs.git/tree/modules/...) suggest that it's going to fail, so I asked Ian once again in the bugzilla for reassurance.
