fs: prepare for "explicit connectable" file handles
We would like to use the high 16bit of the handle_type field to encode
file handle traits, such as "connectable".
In preparation for this change, make sure that filesystems do not return
a handle_type value with upper bits set and that the open_by_handle_at(2)
syscall rejects these handle types.
