be run as part of mts.

Ken Chen 1647f60d66 [NETD-BPF#19] Mainline part of bpf code from netd 
1. Add libnetd_updatable.so in com.android.tethering. The library is
loaded by netd. Currently, it mainly targets on a few functions which
access BPF maps. The functionality may extend in the future.

2. Attach gcroup progs from libnetd_updatable.so.

3. Move (privileged)TagSocket and untagSocket implementation to mainline
module. Combine privilegedTagSocket and untagSocket into a single
function.

4. Split related unit tests from netd_unit_test to
libnetd_updatable_unit_test as well.
