Enable RFC 7217 stable privacy addresses
... on kernels that support this feature. Android property server is
used in combination with SELinux policy to limit access to the
necessary stable secret.
This change also makes some small improvements and fixes to
libnetdutils.
ip -6 addr indicates stable_privacy addresses with "flags 800"
