config_tools: fix pre_launch VM ACPI table 

Current acpi table adopts the DWordAddressSpace to
present the PCI hole above 4G. It is not correct,
because DWordAddressSpace is used to present the
mem space below 4G.
Follow the ACPI spec, modify to QWordAddressSpace here.

Refer: 19.6.22. CreateQWordField (Create 64-Bit Buffer Field)
