[PATCH 4/4] player: explicitly stop+wait for sink death at_exit

[Eric Wong]

This allows me to hit Ctrl-C on a dtas-player(1) process, wait on
termination of the player, and immediately restart it without
worrying about sink conflicts upon restart.

Before this change, sinks would continue running for a bit
(depending on buffer sizes).
