Mike Smith 3713cbff75 Add support for the SIOCGIFHWADDR ioctl, commonly used by
license managers to obtain the host's ethernet address as
a key.

Note that this implementation takes the first hardware address for
the first ethernet interface found, and disregards the interface name
that may be passed in, as linux ethernet devices are all "ethX".
