We generally do _not_ want the same sysexts to be loaded in both initrd and exitrd phases. The environment is completely different and it's unlikely that the same code can be useful in both places. Nevertheless, it can be useful in _some_ cases, for example when the sysexts contains debugging tools. I think we don't need to differentiate between initrds and exitrds through SYSEXT_SCOPE, because the two types are made available in completely different locations and loaded through a different mechanism, with very little chance of an initrd being loaded as an exitrd without an explicit admin action (or the other way around). So let's not complicate our code or definitions by an explicit "exitrd" sysext designator, but just clarify that "initrd" also encompasses exitrds in this context.
