gdm: update useradd settings

Set HOME_DIR back to /var/lib/gdm. If this is not specified, gdm will store its
files in $HOME/.cache. This is pretty ugly because I think this directory should
only be used by real users? Maybe /var/cache would be a better place, because it
would be the system equivalent of $HOME/.cache?

Use tmpfiles.d to ensure /var/lib/gdm is created with the right permissions
even in case /var would be tmpfs
