Update create_scap_delta_tailoring and apply it to OL8 build

[Xeicker]

Description:

• Update cmake to also create default tailoring as RHEL does. This is a tailoring file that includes all the rules not included in DISA benchmark
• Update the script that creates this tailoring profile as it had a bug when multiple rules cover the same STIG ID
• Also the script had an issue that added all rules to the tailoring profile instead of only the ones that wanted to remove

Rationale:

• Add this tailoring file to OL8 rpm
• The pythons script was removing rules of stig profile using the tailoring file, that shouldn't be removed

Review Hints:

I executed this:

## Obtain the stig ids present in the benchmark
$ grep -oP "(?<=>)OL08-00-\d{6}(?=<)" shared/references/disa-stig-ol8-v2r2-xccdf-scap.xml | sort | uniq > covered_ids.txt
## Obtain removed stig ids:
$ grep 'selected="false"' build/ol8/tailoring/ol8_stig_delta_tailoring.xml | grep -oP "(?<=xccdf_org.ssgproject.content_rule_).*?(?=\")" | xargs -i grep -oP "OL08-00-\d{6}" build/ol8/rules/{}.yml | sort | uniq > tailored_ids.txt

## Verified that there aren't stig_ids removed that aren't covered in the benchmark
$ comm -23 tailored_ids.txt covered_ids.txt

Before this update the rules harden_sshd_macs_openssh_conf_crypto_policy and harden_sshd_macs_opensshserver_conf_crypto_policy where removed even when the STIG id OL08-00-010290 is not covered in the DISA benchmark
