GTTF: disable flaky OptionsUITest tests that fail on automation timeouts
GTTF: disable flaky OptionsUITest tests that fail on automation timeouts

OptionsUITest.CommandOpensOptionsTab (bug 64619)
OptionsUITest.CommandAgainGoesBackToOptionsTab (bug 48521)
OptionsUITest.TwoCommandsOneTab (bug 48521)

Those timeouts increase the run time of ui_tests significantly enough
(about 90 seconds per failing test) to use DISABLED instead of FLAKY.

Each of those tests fails about 500 times per week
according to http://build.chromium.org/f/chromium/flakiness-report/
