ps: obtain applet names from other BusyBox processes

Remove the code which passed applet names to child processes using
environment variables.  This only allowed ps to display names for
its ancestors.

Instead attempt to read applet names from the memory of unrelated
processes.

The Microsoft documentation alone wasn't enough to figure out how
to do this.  Additional hints from:
