libxl/ACPI: add missing build dependency

Just like all other object files - wherever *.o is mentioned, *.opic
also needs mentioning to yield consistent behavior. Otherwise make may
decide to (re)build the object before recursion into $(ACPI_PATH)/ (to
update $(DSDT_FILES-y) and ssdt_*.h) was actually finished.
