Malfunctioning AIs whos brain is removed from the core and rehomed in another core will retain their law 0. (#73047)

## About The Pull Request

Currently if you are able to deconstruct a malfunctioning AI, such as
through methods that gib AIs, rehoming the AI in a new core results in
it losing its law 0, but it retains its antagonist datum and combat
upgrades. This is due to the law 0 only being generated when the AIs
gains the antag datum, I've made it so that when a brain with the
malfunctioning AI datum is inserted into an AI core it will re-produce
its law 0.
## Why It's Good For The Game

"Exploit"(?) that could be used to de-malf AIs patched and should cause
less confusion for malf AI players since they wont end up in a situation
where they have no law 0 but have all other malf AI components.
