add no_x11 variant for giflib and libungif

[illogic-al@…]

I have a patch here to include the no_x11 variant in giflib as it does not need it. I've been using it with my own kde portfiles for months now to no ill effect. As the kde4 based ports don't require X, it would be good to have this variant available.

I would also be fine with a x11 variant (as with libungif port)

That + patchfiles-delete patch-gif_lib.h.diff line snuck in. I'm testing the effect of that so it should not be a part of the variant.
