tests/ovs-monitor-ipsec: Remove --no-wait -vreconnect:emer from ovs-vsctl.

tests/ovs-monitor-ipsec: Remove --no-wait -vreconnect:emer from ovs-vsctl.

This fixes a sporadic failure of the testcase, where ovsdb-server.log
contains:

2016-07-21T21:08:22.279Z|00003|jsonrpc|WARN|unix: send error: Broken pipe
2016-07-21T21:08:22.279Z|00004|reconnect|WARN|unix: connection dropped (Broken pipe)

I'm not sure what was the purpose of the original "--no-wait
-vreconnect:emer", but the test seem to run fine without it.
