When we build GIMP with `-Dauto_features=enabled` to ensure we have
fully-featured GIMP and to have it warn us when we are missing some
optional dependency, Meson also enables relocatable bundle.

This is unexpected since being relocatable is a binary property rather
than a feature. This patch switches it option to a combo type to make
it ignore auto_features option.
