Remove dependency on marlin sepolicy

Now that the selinux policy has been split between the system and
vendor partitions the aosp_arm64_ab build variant no longer
depends on the marlin selinux policy to work on marlin and sailfish.

Test: build and flash aosp_arm64_ab system.img on marlin and sailfish
