[PATCH 15/20] signal: Push pid type down into complete_signal.

[Eric W. Biederman]

This is the bottom and by pushing this down it simplifies the callers
and otherwise leaves things as is.  This is in preparation for allowing
fork to implement better handling of signals set to groups of processes.
