Move campus host config into /etc/network/interfaces

Make hosts/campus-host{1,2}_interfaces the source of truth for the
campus host IP and default route, and have clab simply invoke 'ifup
eth1' at container start to apply it. Previously the bound interfaces
file was unused and the real config lived in the YAML exec block,
which was misleading.

BusyBox ifup in the network-multitool image needs 'address' plus
'netmask' rather than a CIDR, so split the address accordingly. Also
add 'post-up ip route replace default via <fabric-gw>' so the fabric
default overrides the management DHCP default even when one is already
installed.

Add Campus EVPN-VXLAN fabric configs and host interfaces

- campus-spine1/2 (AS 66000): eBGP underlay + EVPN RR toward leafs
  and border leafs, addressing plan 10.1.x.x.
- campus-leaf1/2 (VTEP1, AS 66001, VTEP 10.1.255.11): VLAN 50
  (stretched L2 VXLAN, VNI 110050) and VLAN 60 (VRF gold anycast
  10.60.60.1, L3 VNI 100001).
- campus-leaf3/4 (VTEP2, AS 66002, VTEP 10.1.255.12): VLAN 50 and
  VLAN 70 (VRF gold anycast 10.60.70.1).
- border-leaf-campus1/2 (AS 66005, VTEP 10.1.255.21): MLAG pair,
  OSPF + eBGP to cores, VRF gold stitched via vxlan vrf gold
  vni 100001 with RT 1:100001.
- campus-access1/2: L2-only uplinks to campus leaf MLAG pairs,
  trunks VLAN 50+60 / 50+70.
- campus-host1/2 interface files: bond0 + VLAN sub-interfaces for
  the stretched L2 VLAN 50 and the VRF gold subnets.
