When the program child.c does an exec, there's no external indication that the
exec occured; should modify the program so that it, via command line options,
indicates the exec.

* kill/child.c: Implement --filename=<program> argument. For
execve, argv to PID:TID, and pass through --filename=, --wait=.
the value can be seen in /proc/PID/cmdline, but that isn't yet visible via frysk.
