When we install to a non-standard prefix, the Python modules
are not in the standard location requiring the PYTHONPATH
to be fixed up.
This wa a pre-existing issue with suricatasc, and not due to
the move into the python directory.
Will be built and installed as part of the Python code used
for suricatactl, which is intended to be the generic place
for all Python utility code that gets installed with Suricata.
No change to suricatasc code.
Use a new directory, Python to host the Suricata python modules.
One entry point is suricatactl, a control script for
miscalleneous tasks. Currently onl filestore pruning
is implemented.
