Allow a master interface to be specified as one of the parameters when
creating a new interface via rtnl_newlink. Previously this would
require invoking interface creation, waiting for it to complete, and
then separately binding that new interface to a master.
In particular, this is used when creating a macvlan child interface for
VRRP in a VRF configuration, allowing the interface creator to specify
directly what master interface should be inherited by the child,
without having to deal with asynchronous complications and potential
race conditions.
