Refactor VM volume mounting

- Replace bind-mounts on /lmn/media/$USER with separate
  mounting for Home and Share SMB shares in the VM.
- Update vm-run to start virtiofsd with /lmn/media/$USER
  (/home/$USER on localhome machines).
- Use vm-vminfo to generate a JSON file containing user
  information, including Username, Groups, printer list
  krb5-ticket and some more
- Configure vminfo.service (systemd-timer) to periodically
  call vm-vminfo.
- Ensure krb5-ticket (TGT) is injected into the Windows VM.
- Mount SMB-Home and SMB-Share shares as part of the new structure.
