chromeos: Disable inputs.VirtualKeyboardOOBE Tast test on Chrome's bots.

It's failing with "not supplied via -var or -varsfile" errors, which
are a KI when running tast tests on Chrome bots.

This disables the test while we work on supporting these types of tests.

No-try'ing to speed up LKGM updates.
