Remove accuracy bonus when flashlight is enabled (#36900)

When flashlight and reading weren't their own separate skills, pp
bonuses were put into the aim/speed/accuracy values to make them worth
something over nomod. Now that flashlight and hidden are calculated as
their own skills, it doesn't make sense to provide a bonus because
accurate values are calculated in the skills themselves.

The global flashlight skill multiplier was increased to counteract the
slight nerf of removing this bonus.
