syscalls: Use define-as-needed for network-interface syscalls. 

* guix/build/syscalls.scm (network-interface-flags): Use define-as-needed macro
and remove from export list.
(set-network-interface-flags): Ditto.
(set-network-interface-address): Ditto.
(IFF_UP, IFF_BROADCAST and IFF_LOOPBACK): Ditto.
