If the Postfix agent emitted a status line whose first column was empty, the discovery of the Postfix status service crashed during a Check_MK discovery run with TypeError: 'item' must be a non empty string or ommited entirely, got ''.

Such lines are now skipped during parsing, so discovery runs through to completion and the remaining Postfix instances are discovered normally.
