introduces new command "fail2ban-python", as automatically created symlink to python executable, where fail2ban currently installed (resp. its modules are located);

fixed pythonic filters and test scripts (running via "fail2ban-python" now);
fixed test case "testSetupInstallRoot" not for default python (also using direct call, out of virtualenv);
