Rule `firewalld_sshd_port_enabled` does not support offline remediation

[evgenyz]

Description of problem:

Bash remediation of the rule does not support offline mode (namely: Image Builder).

This issue is similar to #11275, but unlike rules mentioned there this one can be fixed by using IB Blueprint remediation.

SCAP Security Guide Version:

master

Operating System Version:

RHEL9.4

Steps to Reproduce:

1. Try to harden an IB image using CIS profile.
2. Image is not properly remediated as bash script aborts in the middle.

Actual Results:

Remediation bails in the middle of the process. Firewall settings for IB images are not fixed.

Expected Results:

Remediation snippet does not break remediation flow. Firewall settings for IB images are fixed using Blueprint remediation.

If we enable sshd service in the image the port should be enabled as well. Also, it is not clear ATM in which situation it'd be necessary to explicitly configure firewalld. I'm removing BLOCKER for now.

The problem with exit in Bash has been fixed.

Actually, I'll just close it.
