Install & config tools/csfcsf.sh auto cronjob by default in 123.09beta01

For fresh Centmin Mod 123.09beta01 and newer initial installs automatically configure /usr/local/src/centminmod/tools/csfcf.sh auto cronjob to update Cloudflare IP whitelisting in CSF Firewall instead of relying on folks to manually do it https://community.centminmod.com/threads/6241/. This has no harm or ill effects for folks who do not use Cloudflare anyway so might as well set it up by default and save folks one extra manual step for each Centmin Mod installation. You can verify it's properly setup cronjob via SSH command listing your cronjobs via:

crontab -l

centmin.sh
