Don't enable DscpPolicyTracker on pre-T devices.
The code cannot work before T because before T the tethering
module can only load BPF programs/maps into /sys/fs/tethering/bpf
and the system server cannot access that directory.
Additionally, this is causing unit tests to fail on pre-T devices
because on those devices the seccomp filter blocks the bpf
syscall from apps (including Java tests).
Test: revert aosp/1907693 and atest FrameworksNetTests:ConnectivityServiceTest
