libsepol: trigger new RTM_GETNEIGH{TBL} behavior
Use one of the policy config bits to tell the kernel to start using
the nlmsg_readneigh on RTM_GETNEIGH and RTM_GETNEIGHTBL messages instead
of the previous behavior of using nlmsg_read.

Test: On Cuttlefish, run combinations of:
- Policy bit set or omitted
- App having nlmsg_readneigh permission or not
Verify that only the combination of the policy bit being set + the app
not having the nlmsg_readneigh permission prevents the app from
sending RTM_GETNEIGH messages.
