Disable flaky ConditionalTabStripTest#testStrip_InfoBarOptIn

The test has been disabled conditionally on x86 emulators, but it's also
failing on arm bots.

This CL disables the test unconditionally.
Similar to https://chromium-review.googlesource.com/c/chromium/src/+/2696421
which disabled related test.
