Subject: [PATCH] top: trade 'look_up_our_self' for a new API equivalent

With the advent of the 'fatal_proc_unmounted' function
in the <pids.h> API to ensure the /proc filesystem was
mounted, we will finally get rid of the last remaining
vestiges of the former libprocps <readproc> interface.

[ also play a little catch up and whack some headers ]
[ that are not necessary now, beyond that readproc.h ]
