Don't send KEY_CHANGED messages if we don't support the legacy protocol.

Browse source 
KEY_CHANGED messages are only useful to invalidate keys for non-SPTPS nodes;
SPTPS nodes use a different internal mechanism (forced KEX) for that purpose.
Therefore, if we know we can't talk to legacy nodes, there's no point in
sending them these messages.
