state_tracker: Fix check for scissor enabled when < 0.
DEQP's clear tests like to give us x + w < 0 or y + h < 0. Since we
were comparing to an unsigned, it would get promoted to unsigned and come
out as bignum >= width or height and we would clear the whole fb instead
of none of the fb.
Fixes 10 tests under deqp-gles2/functional/color_clear.
