migration: Fix analyze-migration.py 'configuration' parsing
The 'configuration' state subsections are currently not being parsed
and the script fails when analyzing an aarch64 stream:
Traceback (most recent call last):
File "./scripts/analyze-migration.py", line 625, in <module>
dump.read(dump_memory = args.memory)
File "./scripts/analyze-migration.py", line 571, in read
raise Exception("Unknown section type: %d" % section_type)
Exception: Unknown section type: 5
