Previously, there was no way to detect when tombstoned processed an
intercept request packet, making it possible for a intercept request
followed by a crash_dump being processed in the wrong order.
Add a response to intercept registration, to eliminate this race.

waitpid(..., __WCLONE) fails with ECHILD when passed an explicit PID to
wait for. __WALL and __WCLONE don't seem to be necessary when waiting
for a specific pid, so just pass 0 in the flags instead.

PTRACE_DETACH is only necessary if the process is in group-stop state,
the tracer exiting is sufficient to detach and resume tracees.
Using this, set a 5 second timer with alarm(2) that just kills us, to
avoid leaving processes stopped.

Remove debuggerd in favor of a helper process that gets execed by
crashing processes.
