The netlink policy unit test contains test fixture data that is
subject to endianness and currently fails on big endian systems.
Store the fixture data in a struct to ensure proper byte order for
the header data.
Also fix improper style for sizeof with expressions.

Data retrieved from netlink and friends may include link layer
address. Add type to nl_attr_type and min/max functions to allow
use of nl_policy_parse with this type of data.
While this will not be used by Open vSwitch itself at this time,
sibling and derived projects want to use the great netlink library
that OVS provides, and it is not possible to safely override the
global nl_attr_type symbol at link time.
