PRESUBMIT: Skip checking Log for customtabs_benchmark

The CCT benchmark is a small app with minimal dependencies and no
proguard. If it includes Chromium java pieces, it would not fit into the
method count limits, so it would need to enable proguard. This is overly
heavy for the purposes of this app. So we would like to use
android.util.Log in this app instead.
