kconfig: gconf: replace GdkColor with GdkRGBA

GdkColor is deprecated with GTK 3.14. [1]

Use GdkRGBA instead.

This fixes warnings such as:

scripts/kconfig/gconf.c: In function ‘set_node’:
scripts/kconfig/gconf.c:138:9: warning: ‘gdk_color_parse’ is deprecated: Use 'gdk_rgba_parse' instead [-Wdeprecated-declarations]
  138 |         gdk_color_parse(menu_is_visible(menu) ? "Black" : "DarkGray", &color);
      |         ^~~~~~~~~~~~~~~
