Include netinet/if_ether.h

Fixes
/path/to/systemd/recipe-sysroot/usr/include/netinet/if_ether.h:101:8: error: redefinition of 'struct ethhdr'
 struct ethhdr {
        ^~~~~~

and related arphdr, arpreq, and arpreq_old errors
/path/to/systemd/recipe-sysroot/usr/include/net/if_arp.h:22:8: error: redefinition of 'struct arphdr'
 struct arphdr {
        ^~~~~~

The latter requires removing some includes of net/if_arp.h to avoid
conflicting with netinet/if_ether.h.
