You are multiply defining localhost and localhost.localdomain. All
there should be is:
127.0.0.1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
But that's not the underlying issue, it's just a complication. What
the 'getent hosts 127.0.0.1' is showing is that the system is either
not retrieving host information from the /etc/hosts file or not
retrieving it all. That same command on my system returns
127.0.0.1 localhost.localdomain localhost
i.e. the line identical to the one in /etc/hosts. Yours doesn't. What
does /etc/host.conf contain - does it have the line 'multi on' in it?

Your nsswitch.conf files shows that you are retrieving information from
sssd for users. (But not for hosts, so it's not relevant here)

Are you running your own named? (I thought you said you were - this
output says you aren't.)
