[gnome-shell] Make gnome-shell-extension-prefs a binary executable

[Florian Müllner <fmuellner src gnome org>]

commit 2dd7db480835e702f53623dbdb776e6aff63e08d
Author: Florian Müllner <fmuellner gnome org>
Date:   Fri Dec 6 21:20:03 2013 +0100

    Make gnome-shell-extension-prefs a binary executable
    
    Since commit 1ebb162a00bf6c4b0 moved JS sources into resources,
    the extension-prefs tool was broken. To fix it, we would either
    need to generate an external GResource in addition to the generated
    C code and teach gjs-console about loading it before evaluating
    the script, or turn gnome-shell-extension-prefs into a binary with
    the JS resources compiled in.
