ospf, ipsec: use different ids for protocols at layer3 (#2838)

Don't use the same id for the same protocol identified via L3 info or
via standard TCP/UDP detection (example: ospf ip_proto 0x59 or TCP port
2604)

Before:
```
ivan@ivan-Precision-3591:~/svnrepos/nDPI(dev)$ ./example/ndpiReader -H | grep -wE 'OSPF|IPSec|AH|ESP|IP_OSPF'
 79       79 IPSec                  UDP        X        Safe         VPN                500,4500                        500
 85       85 OSPF                              X        Acceptable   Network            -                               2604
```

After:
```
ivan@ivan-Precision-3591:~/svnrepos/nDPI(ospf-ipsec)$ ./example/ndpiReader -H | grep -wE 'OSPF|IPSec|AH|ESP|IP_OSPF'
