Introduce a new out-of-source-utils.eclass to carry run_in_build_dir() helper function. This function used to be defined in multibuild.eclass and indirectly exposed through the eclasses using it. However, it is used rather rarely and it is technically also useful for out-of-source.eclass, so it makes more sense for it to be standalone. In the end, eclasses are cheap.
