Hardware Address validation
Summary:
The all zero's and all one's hardware address are reserved.
As such, they should not be used in dhcpcd.
Likewise, Router Solicitation messages should not contain an
all zero source address option.
Fixes T119.
Test Plan:
Request IPv6RA over a PPP interface on a suitable OS which assigns
an all zero's or all one's hardware address.
Maniphest Tasks: T119
