Outliner: tweak handling of liboverrides in delete code.

Essentially, we only allow deletion of hierarchy roots of liboverrides,
when hierarchy deletion option is enabled.

Also add some checking code in the generic, non-object/collection ID
delete code, to prevent any deletion of liboverrides that would be part
of a hierarchy.
