check_snmp: Handle SNMPv3 noAuthNoPriv properly (#1245)

[Anton Löfgren]

The SNMPv3 noAuthNoPriv security level, somewhat unintuitively, requires
a security name to be passed along together with the request. Check_snmp
previously did not do this, causing snmpget to throw an error:

"External command error: No log handling enabled - turning on stderr
logging
snmpget: No securityName specified"

This patch fixes the issue by always providing the security name when
noAuthNoPriv is specified.
