Reuse the same SEPolicy for edgetpu gs101 for gs201.
1. gs101 sepolicy has been refactored into an edgetpu directory, which
is meant to be reused. We only need to match the gs201 side to mirror
that. This CL references Adam's ag/14911633.
2. In a separete CL, add /dev/janeiro into the common gs101 sepolicy.
