Removes Generic Tailstab for Vamp lurker (#6280)

# About the pull request

Removes vampire lurket tail stab ability as it was intended in the
original design.

# Explain why it's good for the game

Tail stab was not supposed to be on the kit of Vamp lurker . the reason
being is that Tail jab is pretty much the same ( tail stab did not exist
when vampo lurker was designed).
it provides vamp with an insane burst of damage if they movestack both
abilities which no good.
