Only the bluetooth app may run in the bluetooth domain

Remove neverallow exemption allowing other processes to run in
the bluetooth app's selinux domain.

The bluetooth domain is intended to host the zygote spawned
bluetooth app. It is not intended to host other bluetooth related
processes. Please define new domains for these processes.

Test: build Marlin
