Revert "gpu: Run trace tests with pixel test browser args"

This reverts commit ab1868c4.

Reason for revert: Breaks sw compositing trace tests on ChromeOS GPU FYI: crbug.com/1129421

Original change's description:
> gpu: Run trace tests with pixel test browser args
>
> Trace tests don't take extra browser args specified by the corresponding
> pixel test into account.  Most tests don't have any extra browser args,
> but a few disable gpu compositing and don't depend on the browser args
> for correctness.  However, an upcoming pixel test will need its browser
> args for correctness:
