use machine version in vga default type selection

If we get an VM machine older than 2.9 we use the old selection
expression for the VGA type. This allows to live migrate VMs to PVE
5.0.
Also once kvm gets updated to 2.9 in PVE 4.4 newly started VMs will
use "std" as default VGA instead of cirrus.
