[fuchsia] Exclude SwiftShader and Vulkan libs from CastRunner.

Removes large libraries that were pulled in as a result of an indirect
but necessary dep on Blink.

The exclusions can be removed along with the Blink MessagePort
dependency, once a fix for crbug.com/1126571 lands and is
integrated with NamedMessagePortConnector.
