remove go-goptlib and go-net

devel/go-tools doesn't depend anymore on net/go-net, leaving only
devel/go-goptlib having a BDEP on it. Both ports are go libraries
that are needed by nothing and that any modernish go port would pull
in via modules anyway.

ok to remove?

is this quirks diff (plus unhook in the makefile and cvs rm) ok/enough?
