test.dart: Stop looping over vmOptions in browser tests to turn the buildbot green.

test.dart: Stop looping over vmOptions in browser tests to turn the buildbot green.

There are some flaky tests in the language suite in component chromium with the dart test script.  They all have multiple vmOptions lines, so temporarily disabling that functionality to turn the build green again.

Filed bug dart:1104.  This may not solve it, since we now have some
cases without vmOptions. http://code.google.com/p/dart/issues/detail?id=1104

File tools/testing/dart/test_suite.dart (right):

optionsFromFile['vmOptions'][0]; {
I think what may be happening is if you specify --flags= multiple times, which
is probably what the buildbot is doing, it only uses the last --flags value
instead of combining them. For example, in my dart command listed here:
http://code.google.com/p/dart/issues/detail?id=1046&can=4&colspec=ID%20Type%2...,
this opens chrome as the test browser, even though I specified "ff." The problem
goes away if I combine all of the --flag options into one flag that is comma
separated. I didn't complain about this because I thought this was your intended
behavior?

This is just a guess, but somehow multiple --flags items do not seem to be
combined correctly.
