New csf v6.22

Changes:

• Security Fix – Sanitised user data input to prevent running unauthorised commands via the UI. A user would require root access to exploit this, so vulnerability is probably low. Thanks to Steven at Rack911.com for reporting this issue
• Added Password ENV variable check to Server Check on cPanel servers
• Update cPanel ACL Driver installations to change force cache update using “touch” instead of removing the cache
• Modified TOR URL in /etc/csf/csf.blocklists to use:
