HALs are intended to be limited responsibility and thus limited
permission. In order to enforce this, place limitations on:
1. What processes may transition into a HAL - currently only init
2. What methods may be used to transition into a HAL - no using
   seclabel
3. When HALs exec - only allow exec with a domain transition.

Test: Build aosp_marlin, aosp_bullhead, aosp_dragon. Neverallow rules
      are compile time assertions, so building is a sufficient test.

Only HALs that manage networks need network capabilities and network
sockets.

Test: aosp_marlin and aosp_bullhead policy builds. Note: neverallow
      rules are compile time assertions and do not change the
      on-device policy.
