ether/slirp: Avoid redefinition of the same constants

eth.h and slirp.h both define ETH_ALEN and ETH_P_IP rtl8139.c and eth.h both define ETH_HLEN Move the related constant (ETH_P_ARP) from slirp.h to eth.h, and remove the duplicates; make slirp.h include eth.h Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Reviewed-by: Alex Bennée <alex.bennee@linaro.org> Signed-off-by: Jason Wang <jasowang@redhat.com>
