Don't create user homedir in the image build

Depending on how Apertis images are deployed (e.g. ostree, lxc or debian) at first boot there may or may not be a home directory for the user anymore. To make things more consistent simply never create the users home directory at image build time, which means in all image types the users homedirectory should be created at first boot.

As a bonus this avoids the ostree commits containing a homedir which will get mounted over.
