Description of problem: 

Open Scap Security Guide Remediation script [ /usr/share/scap-security-guide/bash/ssg-rhel8-role-ospp.sh ]for RHEL8 duplicates entries in the SELINUX configuration file:[ /etc/sexlinux/config ]

Note: ( RHEL 8 Remediation script files)
ssg-rhel8-role-default.sh - Is NOT affected 
ssg-rhel8-role-ospp.sh - Is affected 
ssg-rhel8-role-pci-dss.sh - Is NOT affected


Version-Release number of selected component (if applicable):
scap-security-guide-0.1.42-11.el8.noarch


How reproducible:
Easily Reproducible


Steps to Reproduce:

1. Install SCAP security Guide.
   
    # yum install scap-security-guide

2. Run the scap re-mediation script
   
    # chmod +x /usr/share/scap-security-guide/bash/ssg-rhel8-role-ospp.sh
    # /usr/share/scap-security-guide/bash/ssg-rhel8-role-ospp.sh


3. Check the selinux Configuration file here:
   
    # less /etc/selinux/config



Actual results:

File: /etc/selinux/config 

###BEGIN FILE###

# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
#     enforcing - SELinux security policy is enforced.
#     permissive - SELinux prints warnings instead of enforcing.
#     disabled - No SELinux policy is loaded.
SELINUX=enforcing
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected. 
#     mls - Multi Level Security protection.
SELINUXTYPE=targeted



# Per CCE-CCE-80868-3: Set SELINUXTYPE=targeted in /etc/sysconfig/selinux
SELINUXTYPE=targeted

# Per CCE-CCE-80869-1: Set SELINUX=enforcing in /etc/sysconfig/selinux
SELINUX=enforcing

###END FILE###

Note: It appends two duplicate entries to the file after script is ran.
SELINUXTYPE=targeted
SELINUX=enforcing


Expected results:

Script should not be adding additional SELINUX entries [ SELINUXTYPE=targeted , SELINUX=enforcing ] into the selinux configuration file.
