Rule logind_session_timeout is misaligned with DISA

#### Description of problem:
Rule logind_session_timeout is misaligned with DISA STIG for RHEL 9 V2R7. We discovered this issue in weekly productization.

The problem is that CaC check finds the setting in the directory `/etc/systemd/logind.conf.d` at `/etc/systemd/logind.conf.d/oscap-idle-sessions.conf` but DISA requires it to be present in the `/etc/systemd/logind.conf`.
