tests: bgp_evpn_mh timing issue fix

This test is failing locally for me 100% of the time
since zebra was converted to mgmtd usage.  The failed
command is:

torm11# show evpn mac vni 1000 mac 00:00:00:00:00:11 json
{
  "00:00:00:00:00:11":{
    "type":"auto",
    "uptime":"00:02:01",
    "localSequence":0,
    "remoteSequence":0,
    "detectionCount":0,
    "isDuplicate":false,
    "syncNeighCount":0,
    "neighbors":{
      "active":[
      ],
      "inactive":[
        "45.0.0.11"
      ]
    }
  }
}

The test is expecting an esi as a key in the output.  Re-arranging
the startup of the tor's before the hosts fixes the issue.
