Revert "Support skipping successful test suites in chromium_trybot"

This reverts commit 4bf1014d44fc1f2683fb20759cde7d0043f2187f.

Reason for revert: spec reverting for crbug.com/1521507

Original change's description:
> Support skipping successful test suites in chromium_trybot
>
> The recipe does skip tests like it should now, but does not preserve
> the test step to make it obvious the tests are being skipped. Move
> the searching for skipped tests logic into chromium_tests so the
> targets config handles the skipping logic
>
> Example Led builds:
> chromium_trybot: https://ci.chromium.org/ui/p/chromium/builders/try.shadow/linux-x64-castos/82/overview
> orchestrator: https://ci.chromium.org/ui/p/chromium/builders/try.shadow/linux-x64-castos/82/overview
> compilator: https://ci.chromium.org/ui/p/chromium/builders/try.shadow/linux-rel-compilator/2335/overview

Recipes

If you're here to make a change to ‘recipes’ (the code located in the recipes directory), please take a look at the README for more information pertaining to recipes.

Style

The preferred style is PEP8 with two-space indent; that is, the Chromium Python style. Functions use lowercase_with_underscores, with the exception of the special functions RunSteps and RunTests in recipes. Use yapf (git cl format --no-clang-format) to autoformat new code.
