out-of-source-utils.eclass: New utility eclass
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.
