pkgconfig: add patch to disable legacy scripts such as glib-config

On an F13 host with glib-config installed pkgconfig-native can get into a
horrible state with recursive calls between pkg-config and glib-config.
The patch adds a configure time option to disable legacy script support in
pkgconfig and makes use of the option for Poky.
