[cogl] cogl-pango-pipeline-cache.c: Include forgotten header

[Neil Roberts <nroberts src gnome org>]

    cogl-pango-pipeline-cache.c: Include forgotten header
    
    The private header is needed as the cogl_texture_get_format API was made
    private, so that C4013 (implicit declaration of ...) warnings/errors can
    be avoided
