Remove master key extraction from tls_connection_get_keys()

Browse source 
This is not needed anymore with the tls_connection_prf() being used to
handle all key derivation needs. tls_connection_get_keys() is a bit
misnamed for now, but it is only used to fetch the client and server
random for Session-Id derivation.
