hw/arm/virt-acpi-build: Don't create ITS id mappings by default

Browse Source 
Commit d6afe18b72 ("hw/arm/virt-acpi-build: Fix ACPI IORT and MADT tables
when its=off") moved ITS group node generation under the its=on condition.
However, it still creates rc_its_idmaps unconditionally, which results in
duplicate ID mappings in the IORT table.
