Make Gold tests always use --passfail

Makes all uses of Skia Gold for the GPU pixel tests always pass
--passfail to goldctl. The way the GPU tests use Gold (per-test uploads
instead of batched uploads) requires that --passfail always be passed,
so not doing so just results in unhelpful errors and images not being
uploaded to Gold when they should be.
