devel/cmake: add patch to Modules/FindOpenGL

In order to use libEGL, it looks for libOpenGL, but NetBSD and pkgsrc's
MesaLib don't have that, they have libGL instead. This causes issues in
x11/wxGTK32. See
https://github.com/wxWidgets/wxWidgets/issues/22841

+Despite complicated wording in the module, pkgsrc's MesaLib has no libOpenGL
+but does have (conditionally) libGL. Possibly all conditions and dependencies
