Run the Tast-based MTBF performance CUJ test.

Tast is an integration-testing framework analogous to the test-running portion
of Autotest. See https://chromium.googlesource.com/chromiumos/platform/tast/ for
more information.

See http://go/tast-failures for information about investigating failures.
