networkd: add support for vxlan Remote and Local.

This patch add supports to configure IFLA_VXLAN_LOCAL
and IFLA_VXLAN_GROUP.

The "Group" is renamed to "Remote" which is a multicast address.`

```
Description=vxlan-test
Name=vxlan1
Kind=vxlan

[VXLAN]
Id=33
Local=2001:db8:2f4:4bff:fa71:1a56
Remote=FF02:0:0:0:0:0:1:9
```

output
```
