Removes the martyr and hijack objs, again. Also removes some heavily disruptive spy OBJs (#3343)

## About The Pull Request

See name, removes the martyr and hijack objs from traitor and spy

## Why it's good for the game

Giving these out for free on a random chance on the most common antag
types is a bad idea. Especially when it gives the potential
justification to bypass the station integrity rule. Also it's a mess to
admin + we aren't trying to be Manuel, despite what it might seem like
at times.
