reduce.py: Allow reducing error messages, print output in case of error (#2179) 

* reduce.py: Allow reducing error messages, print output in case of error

Allow reducing code that triggers (false positive) error messages.
Print Cppcheck output in case Cppcheck returns unsuccessfully and no
segfault is expected. This helps fixing messed up command lines (for
example issues with the path).

* Use "else" as suggested
