[gobject-introspection] Require libffi.pc

[Colin Walters <walters src gnome org>]

commit 494c1c92520917999407832453c11c2247b4e7bb
Author: Colin Walters <walters verbum org>
Date:   Wed Dec 2 17:56:05 2009 -0500

    Require libffi.pc
    
    We use it for girffi.h.  Remove the code to detect libffi without the .pc
    file.  If you don't have it, get it.
