agent: Use new libassuan API for pipe server process.

Browse source 
* agent/call-daemon.c (struct wait_child_thread_parm_s): Remove PID
field.
(wait_child_thread): Don't touch the internals but call
assuan_pipe_wait_server_termination.
(daemon_start): Don't use PID.
(agent_daemon_dump_state): Don't use PID.
* agent/call-pinentry.c (watch_sock): Call assuan_pipe_kill_server.
(agent_popup_message_stop): Likewise.
