[Feature Request] - Support non-Debian Based Distributions

[latetedemelon]

There are a few Debian specific checks which could be expanded upon to be more agnostic. From the reddit thread:

• The SSH Configuration checks are only in /etc/ssh/sshd_config but these could also be present in a file in /etc/sshd/sshd_config.d.

• UFW is not present on all systems. Other systems may have firewalld or even plain iptables or nftables.

• Assumes the server is Debian based: https://github.com/vernu/vps-audit/blob/main/vps-audit.sh#L119

• Many systems have ss instead of netstat: https://github.com/vernu/vps-audit/blob/main/vps-audit.sh#L137

• Not every system logs auth failures in /var/log/auth.log, and it could be /var/log/secure on some systems: https://github.com/vernu/vps-audit/blob/main/vps-audit.sh#L109

Furthermore, there are two calls to dpkg, and another one to apt-get, which are not universally available.
