Suppress untrusted touches toast for Snapchat

We are aware of the issue (b/173297887) and working on a fix, however
the toast is annoying dogfooders and the app compat reset only lasts
during a reboot lifecycle.

Bug: 158002302
Bug: 173297887
Test: Open Snapchat, try to trigger toast, see logcat message and no
      toast.
