Subject: plugins/check_snmp: Show snmp error when we fail to parse its output

Dying without a hint of what went wrong is just plain annoying. With
this patch we at least get a hint.

While at it, we fix the string offset so the output we're interested
in doesn't keep the equal sign that snmpget prints.
