Set should_retry_with_patch=false for Chromium GPU tests.

The GPU tests act much like integration tests for the entire browser,
and tend to uncover flakiness bugs more readily than other test
suites. In order to surface any flakiness more readily to the
developer of the CL which is introducing it, we disable retries with
patch on the commit queue.
