sci-geosciences/gpsbabel: drop use gui, add use qt6

Though the build system provides separate targets for
the gui and cli tools, the cmake configure files do not
reflect this and they will search for qt unconditionally.
Patching is non-trivial because the source files for the
gui and for the cli are not completely separated.

The package does support qt6 but the upstream cmake files
do not provide a means of selecting which to use and will
choose a version automagically. A simple patch is enough
to fix this.
