[testing] autopkgtests failure for report_disabled_parsers.py:ReportDisabledParsersTest.test_local_ip_not_obfuscated

In preparation of avocado landing in Debian and Ubuntu (which is due to land in a week or so), I have been doing some tests in our test environments, and we get the following issue

(007/276) tests/cleaner_tests/report_disabled_parsers.py:ReportDisabledParsersTest.test_local_ip_not_obfuscated:  FAIL: Content '127.0.1.1' does not appear in /var/tmp/avocado_4k2ol_orsos_tests.py.ReportDisabledParsersTest/sosreport-ReportDisabledParsersTest/sosreport-host0-2025-03-24-vlozhxk/ip_addr\n1: lo    inet 127.0.0.1/8 scope host lo\       valid_lft forever preferre... (13.42 s)

This issue has been created to track the issue so that it's not lost, and will form a fix soon.

So, I've figured this out

When creating new instances we have the following whether it's rocky, or ubuntu

Hosts file

[root@rocky9-01 ~]# cat /etc/hosts
127.0.1.1	rocky9-01
127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4
::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

Use the pythonic way to get IP

[root@rocky9-01 ~]# python3
Python 3.9.21 (main, Dec  5 2024, 00:00:00) 
[GCC 11.5.0 20240719 (Red Hat 11.5.0-2)] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import socket
>>> print(socket.gethostbyname("rocky9-01"))
127.0.1.1

Check the current ip addresses

[root@rocky9-01 ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
    inet 127.0.0.1/8 scope host lo
       valid_lft forever preferred_lft forever
    inet6 ::1/128 scope host 
       valid_lft forever preferred_lft forever
2: enp5s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP group default qlen 1000
    link/ether 00:16:3e:64:77:58 brd ff:ff:ff:ff:ff:ff
    inet 10.201.177.69/24 brd 10.201.177.255 scope global dynamic noprefixroute enp5s0
       valid_lft 2514sec preferred_lft 2514sec
    inet6 fe80::216:3eff:fe64:7758/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

So based on the above, the test would fail
