Fix snmp result

[jjnicola]

What:
Only return the value and do not stop in the first \n.

Why
The response includes the OID, which is not desired.

How:
Running the following script again a snmp agent, the response should not include the OID.

oid = '.1.3.6.1.2.1.1.1.0';
protocol = 'udp';
port = 161;
community = 'public';

display("version 1");
ret = snmpv1_get( port:port, oid:oid, protocol:protocol, community:community );
display (ret, "\n");
