Fix home permission on NetBSD
Permissions on homedir can end up being completely empty on gcc300 (NetBSD):
# ls -lha /home/foo/ total 19K d--------- 3 foo users 512B Mar 22 20:24 .
This happens when we let ansible create
~/.ssh to store a SSH key while the user does not exist yet. Ansible creates the parent directory but with empty permissions.
Note: we use an old version of ansible.
