donate-cpu.py: Add '--test' parameter for testing against local server. (#1559)

Similar to the '--test' option for the donate-cpu-server.py script that lets the server listen locally on port 8001 the client now can also work against such a server by using the same option '--test'.

 #  -jN                  Use N threads in compilation/analysis. Default is 1.
 #  --package=url        Check a specific package and then stop. Can be useful if you want to reproduce some warning/crash/exception/etc..
 #  --stop-time=HH:MM    Stop analysis when time has passed. Default is that you must terminate the script.
 #  --work-path=path     Work folder path. Default path is cppcheck-donate-cpu-workfolder in your home folder.
+#  --test               Connect to a donate-cpu-server that is running locally on port 8001 for testing.
