Description of problem:
During the test , observed the /etc/os-release file was updated with all the contents(multiple lines of data) of branded_name file,but the contents in the branded_name file was updated with
the product name after the next cert update, but /etc/os-release file
continued to display the old data as well

Version-Release number of selected component (if applicable):
 rpm -qa | grep initscripts
initscripts-9.49.7-1.el7.x86_64

subscription-manager version
server type: Red Hat Subscription Management
subscription management server: 0.8.33-1
subscription-manager: 1.10.7-1.el7
python-rhsm: 1.10.6-1.el7

How reproducible:
3/3


Steps to Reproduce:
1. Manually added a new line "testing new line of data" in branded_file name
 
[root@dhcp70-124 product]# cat /var/lib/rhsm/branded_name
Awesome OS Server Bits
testing new line of data

2.[root@dhcp70-124 product]# cat /etc/os-release
NAME="Red Hat Enterprise Linux Server"
VERSION="7.0 (Maipo)"
ID="rhel"
VERSION_ID="7.0"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:redhat:enterprise_linux:7.0:beta:server"
 
REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 7"
REDHAT_BUGZILLA_PRODUCT_VERSION=7.0
REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux"
REDHAT_SUPPORT_PRODUCT_VERSION=7.0
PRETTY_NAME="Awesome OS Server Bits
testing new line of data"

3. DO any cert update operations like removing subscription, add a new subscription etc

I did a cli attach to trigger the entitlement cert update, to update the branded_name file content
[root@dhcp70-124 product]# subscription-manager attach --pool 8ac6a362425a296701425a29d24507c9
Successfully attached a subscription for: RAM Limiting Package (4GB stackable)

4.the branded_name file is updated with the installed product name , the new line was removed from the branded_name file

[root@dhcp70-124 product]# cat /var/lib/rhsm/branded_name
Awesome OS Server Bits

5.But the /etc/os-release file continued to display the newline details, which wasnt there in the branded_name file after the cert update
[root@dhcp70-124 product]# cat /etc/os-release
NAME="Red Hat Enterprise Linux Server"
VERSION="7.0 (Maipo)"
ID="rhel"
VERSION_ID="7.0"
ANSI_COLOR="0;31"
CPE_NAME="cpe:/o:redhat:enterprise_linux:7.0:beta:server"
 
REDHAT_BUGZILLA_PRODUCT="Red Hat Enterprise Linux 7"
REDHAT_BUGZILLA_PRODUCT_VERSION=7.0
REDHAT_SUPPORT_PRODUCT="Red Hat Enterprise Linux"
REDHAT_SUPPORT_PRODUCT_VERSION=7.0
PRETTY_NAME="Awesome OS Server Bits"
testing new line of data"  <<<<======previous content

Actual results:
Here the new line of data in the branded_name file was updated with
the product name after the cert update, but /etc/os-release file
continued to display newline data(Previous).

Expected results:
SHOULD ignore anything except the first line of /var/lib/rhsm/branded_name as per https://docspace-old.corp.redhat.com/docs/DOC-153859
