homed: include actual fs type + access mode as part of "status" section of user record

So far we have two properties for the intended fstype + access mode of
home dirs, but they might differ from what is actually used (because the
user record changed from the home dir, after it was created, or vice
versa). Let's hence add these props also to the "status" section of user
record, which report the status quo. That way we can always show the
correct, current settings.
