x11-libs/gtk-fortran: Add NO_BUILD_HL cmake option. Disable build gtkf-sketcher

-Patch is disable building of 'gtkf-sketcher' - it isn't installed
and has now documentation.

- Add upstream 'NO_BUILD_HL' cmake option to disable build of
high-level interface to gtk-fortran that is used by plplot interface
(and gtkf-sketcher) and currently causes the TEXTREL QA warnings.
