    cogl/configure.ac: fix pkg-config checks
    
    This fixes the gdk-pixbuf check to not mistakenly check for the "xi"
    package instead of gdk-pixbuf and remove a spurious listing "gl" in
    COGL_PKG_REQUIRES which should only be there when we are using using
    opengl not if we are using gles.
