Subject: networkd: vxlan require Remote= to be a non multicast address (#8117)
Remote= must be a non multicast address. ip-link(8) says:
> remote IPADDR - specifies the unicast destination IP address to
> use in outgoing packets when the destination link layer address
> is not known in the VXLAN device forwarding database.
Closes #8088.
