vmix run command, virtio-drivers template, delay-oobe-run flag

Browse source 
CLI:
- `vmix run <qcow2>` boots image with QEMU (SDL if DISPLAY, snapshot mode)
- --generalize supports delay-oobe-run=true to defer OOBE + activation
  to first boot on real hardware (for physical disk deployments)

Templates:
- essentials.virtioDrivers: installs VirtIO drivers only (no guest agent)
  used in laptop bundle for network access during Office download
- generalize: delayOobeRun flag controls sysprep /shutdown vs /reboot
  delays OOBE, user creation and HWID activation to target device

Build:
- suppress XDG_RUNTIME_DIR and homeless-shelter warnings in SDL mode
- remove invalid ICH9-LMB global properties
