Ling/Vamp/WW npc eating changes

RIP being able to DNA sting the entire station into Shitty Bill.

Also honestly this is a massive nerf for wolves which really don't need one, especially on the population that main gets.

 This is the other part. It’s a nerf to the 3 of the weakest overall antags (sleeper agent and conspirators aside.) To compare it to a meme from Dead by Daylight. The Nurse has been over performing at the highest levels in response we have nerfed the Pig.
