hw/display/cirrus_vga_isa: Disable global_vmstate by default for new machines

Browse Source 
In the long run, we would like to get rid of the code that allows to
register migration state globally, so set global_vmstate to false when
using the isa-cirrus-vga device with new machines, and only enable it
for older machines to avoid breaking the migration there.
