migration: Fix analyze-migration read operation signedness

The migration code uses unsigned values for 16, 32 and 64-bit
operations. Fix the script to do the same.

This was causing an issue when parsing the migration stream generated
on the ppc64 target because one of instance_ids was larger than the
32bit signed maximum:

Traceback (most recent call last):

    classdesc = self.section_classes[section_key]
KeyError: ('spapr_iommu', -2147483648)
