Disable BrowsingDataRemoverBrowserTest.StorageRemovedFromDisk on CrOS.

The PRE_* test fails, while the non-PRE test passes, causing
browser_tests to fail on bots (but the build remains green):
https://ci.chromium.org/p/chromium/builders/ci/linux-chromeos-rel/34103

See crbug.com/1045100 for fixing the build status report.
