Modified Files:
        src/sys/kern: kern_sig.c

Log Message:
Remove unused code branch in the signal code

Remove the ppsig argument from proc_stop_done() and from sigswitch().

This functionality was used in now gone filesystem tracing feature (/proc).
It prevented emitting signal child signals to a debugging program, namely
with the SIGCHLD signal.

The modern solution to perform tracing without signals in a debugger is
to spawn a debugging server and outsource the tracing functionality to it.
This is done in software like gdb-server, lldb-server etc.

No functional change intended.
