vp8enc: Set VP8E_SET_CPUUSED to 0

Browse source 
This setting controls how much CPU can be used by the encoder, specified
in fractions of 16. Negative values mean strict enforcement of this
while positive values are adaptive.

The default value is -4, which means that we're not running as fast
as possible and probably are wasting some quality. 0 is the recommended
default by libvpx upstream.
