Fix bare-metal detection in iommu-setup

Browse Source 
systemd-detect-virt prints "none" on bare metal but exits non-zero, so the
`|| echo "none"` fallback appended a second "none" and the check wrongly
treated a physical Proxmox host as virtualized. Capture the command output
directly and only block when a real virtualization type is reported.
