The error reporting mechanism of special agents only reports the last line of stderr to the checkmk user interface.

For agent_ipmi_sensors the error provided by ipmitool or freeipmi was simply handed over, but contained a trailing \n.

This lead to the situation, that the error '. was reported.

Now, before handing the errors over, the \n are replaced so the error fits in a single line.
