Don't recompute auras of each and every entity globally upon playerdefeat, but only all player auras (for simplicity, and the affected units, structures upon OwnershipChange), refs 6d318d0869 / D12.

The next diff changes this to a global message subscription, so that it
is easier to recognize.

Fixes #5099.
