Remove gpsys1

I'm not quite sure of the purpose of this utility, nor, apparently, is
any readme or historical repo.

Apart from a small fix provided in
commit 71d67305,
there has been no modification to this file since at least 2008. More
importantly, I'm not quite sure of any reasonable use for this file. The
supported platforms are only linux, darwin, or sunos5, and the listed
use, of printing the memory size in bytes, is trivial on any of those
systems without resorting to some python script that wraps a command line
call.

Given that it hasn't been updated since 2008, it's still compatible with
some ancient version of python, which means that it's yet another file to
upgrade to python 3 - in this case, let's drop the program, rather than
bother upgrading it.
