line_length example is failing

[hiker]

The CI test uses make, which works, but the instructions also state that you should be able to run runme.py, but that doesn't work anymore:

/psyclone/examples/line_length$ python ./runme.py 
Traceback (most recent call last):
  File "/home/joerg/work/psyclone/examples/line_length/./runme.py", line 7, in <module>

TypeError: generate() got an unexpected keyword argument 'kernel_path'
