Remove brobocop lawset from robotics fabricator

[Emimiyu]

The law feel ambiguous but people are using the lawset as "asimov but silicons can hunt antagonist now". People use it as a way to encourage sillicons to act like sec, which add mores hurdle to antagonist. Another reason would be, I don't think a "cop" law fit the server culture.

It's also put next to NT lawset, that kinda resemble Asimov, which makes people think brobocop lawset is the equivalent of "asimov".
