Sync up PRESUBMIT.py with Chromium CQ config.

Sync up PRESUBMIT.py with Chromium CQ config.

Now 'git cl try' should trigger exactly the jobs that CQ expects.
Once these pass, CQ should commit immediately.

R=phajdan.jr@chromium.org
BUG=None
TEST=git cl try (succeeded); subsequent CQ run should commit immediately.

PTAL.

This CL was prompted by https://codereview.chromium.org/751613004/ when CQ
started more jobs after all 'git cl try' jobs have succeeded.

LGTM w/ optional comment.

PRESUBMIT.py:1752: builders.extend(['cros_x86'])
I think this builder no longer exists, consider also removing this block.

Addressed the comment, will run 'git cl try' before CQ to test the sync-up
end-to-end.

Indeed, I can't find it in the builders list. Incidentally, with the existing
master map, this bot wouldn't be mapped to any master and wouldn't work anyway.

Removed cros_x86 entirely.

Worked as advertised! Yay :-)

A few extra bots are experimental CQ bots that don't count:

android_clang_dbg_recipe_experimental
linux_chromium_asan_rel_ng
win8_chromium_ng
win_chromium_compile_dbg_ng
win_chromium_x64_rel_ng
win_chromium_rel_ng.
