Some Automatus tests fail for unknown reasons on RHEL

[comps]

Description of problem:

We currently track these as "fail for unknown reasons" when executed via Contest's /per-rule (on a vanilla RHEL virtual machine, not install_vm.py):

All RHELs:

accounts_password_set_max_life_root/correct.pass
accounts_password_set_max_life_root/wrong.fail
postfix_client_configure_mail_alias/correct.pass

RHEL-8 only:

grub2_audit_backlog_limit_argument/correct_grubenv.pass
grub2_password/invalid_username.fail
harden_sshd_ciphers_openssh_conf_crypto_policy/stig_correct.pass
harden_sshd_ciphers_openssh_conf_crypto_policy/stig_correct_followed_by_incorrect_commented.pass
sudo_add_umask/0027_var_multiple_values.pass

---

Further, additional rules/tests fail for semi-known reasons - my limited investigation suggests these try to install packages non-existent on RHEL, or start services that don't exist.

All RHELs:

package_quagga_removed/package-installed.fail
package_rsh-server_removed/package-installed.fail
package_rsh_removed/package-installed.fail
package_mcafeetp_installed/package-installed.pass

RHEL-9 only:

package_xinetd_removed/package-installed.fail
package_ypbind_removed/package-installed.fail
package_ypserv_removed/package-installed.fail
service_telnet_disabled/service_disabled.pass

Please investigate why these fail - typically it's not straightforward (no output from the shell scripts), unfortunately.
