This is a bit dirty, but there is no official API call for this.

if the get_binary_acl does not work for some reason, another approach could be:
- borg create: archive ALL xattrs (including the ones used for ACLs)
- borg extract: skip extracting the xattrs for acls, because acl functions will be used to create these
- borg mount: just list/get all xattrs as archived now in the item and check if ACLs work then.

Junie (AI) experiment + some fixes the AI was not clever enough for.
But, tests fail - anyone wants to review this?
