Thereby fix apparmor issue.

It is no longer required, because...
existing linux user accounts:
* Get permission lock down because security-misc `debian/security-misc.postinst` calls `/usr/lib/security-misc/permission-lockdown`.
new linux user accounts (created at first boot):
* security-misc `/usr/share/pam-configs/mkhomedir-security-misc` pam mkhomedir sets secure permissions using `umask=027`.
