fix(factions): override_faction 0 keeps the template's factions

The client (LWODestroyableComponent::LoadConfigData 0x00c44cb0) uses a
level object's set_faction only when override_faction is absent or true;
with override_faction=0 LoadDataFromTemplate (0x00c9f900) puts the
DestructibleComponent factionList back. 2948 level objects have
override_faction=0, and DLU applied their set_faction anyway. The
resolution is now DestroyableComponent::GetLevelFactions, with tests.
No wire change.

In game: enemies and smashables placed in levels with a set_faction but
override_faction=0 (most smashables, many enemies) are targeted and
aggro as before for the common case; check a few enemies in AG/GF/FV
still fight you and friendly objects are not attacked, and that
smashables still smash and give credit.
