Greatly simplify flags for test binaries.

Since we're now calling the shots of what flags get passed in the
recipes, we can just pass the right ones right away and remove all
the flag renaming.

--isolated-script-test-output is no longer passed, so we can just
remove it. The recipe is currently passing
--isolated-script-perf-test-output but I will start passing the
underscore version shortly.
