Change applicability of rules configuring idle session timeouts (going to master branch)

[vojtapolasek]

This is a port of #10127 to the master branch

Original description and rationale follows.

Description:

• create new OVAL definition checking if installed OS is RHEL
• create three new platforms checking if RHEL >= 8.7, if RHEL <=8.5 and RHEL == 9.0
• use these platforms to limit applicability of logind_session_timeout and sshd_set_idle_timeout

Rationale:

The Systemd feature which can configure session idle timeout is not present in all RHEL releases, therefore the rule does not apply in some cases. To be exact, the feature works only in 9.1 and up and 8.7 and up.
Also the SSH configuration used by sshd_set_idle_timeout has effect only in some cases. It works only up to 8.5.

Testing hints:

• build RHEL 8 and RHEL 9 content
• test the following (you can artifically modify RHEL version by editing the ID within /etc/os-release):
• logind_session_timeout should apply on 8.7 and higher with exception of 9.0
• sshd_set_idle_timeout should be applicable on 8.5 and lower.
• consequently, none of these rules would be applicable on 8.6.
