test this to the fullest extent.

* dissect: when we discover squashfs, don't claim we had a "writable" partition
in systemd-dissect
* set LockPersonality= on all our services
* Add AddUser= setting to unit files, similar to DynamicUser=1 which however
creates a static, persistent user rather than a dynamic, transient user. We
can leverage code from sysusers.d for this.
