  sst: add timer extension to Require for replies

RFC 4028 states that if the UAS does not support Session Timers, a proxy
can add the Session-Expires header initially negociated in the reply, but
must also add the "timer" extension in the Require header.

Thanks go to Eric Tamme (lirakis) for reporting this
