sshpeer: use peer interface

We need the same @property conversion of ui like we did for localpeer.
We renamed _capabilities() to capabilities() to satisfy the new
naming requirement.

However, since we're inheriting from wireproto.wirepeer which inherits
from peer.peerrepository and provides its own code accessing
_capabilities(), we need to keep the old alias around. This wonkiness
will disappear once wirepeer is cleaned up in subsequent commits.

We also implement methods for basepeer that are identical to the
defaults in peer.peerrepository in preparation for the removal of
peerrepository.
