Description of problem:

Host is failing to create '~root/.ssh' from `kickstart default` template while provisioning the host.

How reproducible:

Always

Is this issue a regression from an earlier version:

Yes, It worked earlier in Satellite stream snap 68 and 6.15.3

Steps to Reproduce:

1. Configure a Satellite for provisioning setup, where remote_execution_ssh_user is default set as root

2. Create a host with "remote_execution_ssh_keys" host param to add a public key to the host

3. After host is provisioned, try running a REX job on it

Actual behavior:
 REX job fails because after host is provisioned '~root/.ssh' is missing, no public keys are added in ~/.ssh/authorized_keys, warnings can be seen in `install.post.log` file on host,

chmod: cannot access '/root/.ssh': No such file or directory

{{chmod: cannot access '/root/.ssh/authorized_keys': No such file or directory }}

{{chown: cannot access '/root/.ssh': No such file or directory }}

/sbin/restorecon restorecon: lstat(/root/.ssh) failed: No such file or directory

Expected behavior:
After is provisioned successfully, REX jobs can be run, and ~root/.ssh directory exists with ~root/.ssh/authorized_keys file present
