svga: fix unnormalized->normalized texture coordinate conversion
Sometimes, converting unnormalized coordinates to normalized
coordinates requires an epsilon value to produce the right texels with
nearest filtering. Adding 0.0001 to the coordinates when the min/mag
filter is nearest fixes the issue.
Fixes piglit test fbo-blit-scaled-linear
Tested with mtt-piglit, mtt-glretrace
