Move the module cache files below libdir

These files contain architecture-dependent paths, and thus placing
them into sysconfdir causes unnecessary hassle. Now the immodule cache
file is looked for in libdir/gtk-3.0/3.0.0/immodules.cache, and the
pixbuf loader cache is looked for in libdir/gtk-3.0/3.0.0/loaders.cache.
