When receiving a SIGTERM wait() for children
When traffic_cop receives a SIGTERM it does not wait for it's children to
die
When running under upstart for instance this can lead to a new traffic_cop
instance being started while the old instance's traffic_manager and _server
are still up and running.

traffic_cop: wait() for children on SIGTERM
rework traffic_cop's signal handling to register a handler for
SIGTERM. In this handler we now send SIGTERM to all children
and then wait() for them.
This should allow us to handle restarts in upstart more gracefully.
Finally, we simplify the handling on Linux by no longer parsing
/proc: It's not necessary. Linux is a POSIX system too.

cleanup: get rid of ink_killall implementation
After ripping it out from the code, remove it the Linux-specific,
/proc parsing ink_killall implementation.
