gpxe: delete long since obsolete snapshot of gPXE
gPXE has been deprecated in favor of iPXE for many, many years now.
It is much better than users get it directly from the iPXE project,
since we should no longer need any special modifications for Syslinux
use.

==================================================
Remove it for now since it doesn't seem to be mandatory and
we can use pxelinux.0 for now.
