* Don't wait for p2p-server thread (mimblewimble#2917)

Currently p2p.stop() stops and wait for all peers to exit, that's
basically all we need. However we also run a TCP listener in this thread
which is blocked on `accept` most of the time. We do an attempt to stop
it but it would work only if we get an incoming connection during the
shutdown, which is a week guarantee.

This fix remove joining to p2p-server thread, it stops all peers and
makes an attempt to stop the listener.

Fixes [mimblewimble#2906]
