gdk-pixbuf: move gdk-pixbuf-query-loaders to $libdir for multilib safety

If for example gdk-pixbuf and lib32-gdk-pixbuf are in an image then only one
${bindir}/gdk-pixbuf-query-loaders will be installed, so only one variant will
actually be usable.

Solve this by moving gdk-pixbuf-query-loaders into ${libdir} as it's intimately
tied to the library and rarely directly invoked by the user, and update the
callers to use the right path.
