fix build: exclude bluetooth from neverallow restriction

Bluetooth is sometimes started from init.

Addresses the following compiler error:

  libsepol.report_failure: neverallow on line 489 of
  system/sepolicy/domain.te (or line 9149 of policy.conf) violated by
  allow init bluetooth:process { transition };
  libsepol.check_assertions: 1 neverallow failures occurred
  Error while expanding policy

(cherry-picked from commit 7e380216)
