healthcheck script needs to be spawned from right location

[Senthilnathan Murugappan]

Agent is trying to spawn health_check script from /opt/contrail/utils dir whereas the script is actually at /usr/share/contrail-utils

root@a2s42:~# dpkg -S contrail_vrouter_agent_health_check.py
contrail-utils: /usr/share/contrail-utils/contrail_vrouter_agent_health_check.py

root@a2s42:~# tail -2 /var/log/contrail/contrail-vrouter-agent.log
