    selftests/tdx: skip when the TDX guest device is absent
    
    verify_report fails outside a TDX guest, where /dev/tdx_guest does not
    exist.
    
    Skip only when the device node is missing, so that a real open()
    failure, EPERM or EBUSY, still fails the test instead of being
    reported as a skip.
