Reland virtual test-suite for streaming-preload.

This is a reland of 7c10d9bb.

We just need to add SlowTest entries for the failing tests (already
done for default)

Original change's description:
> Revert virtual test-suite for streaming-preload.
>
> Causes too many timeout issues for WebKit Linux Trusty MSAN.
>
> This reverts the virtual suite part of [1].
