[PATCH 2/2] analyze-migration.py: fix extract contents ('-x') errors

[Laurent Vivier]

When we try to use 'analyze-migration.py -x' with python3,
we have the following errors:

  Traceback (most recent call last):
    File "scripts/analyze-migration.py", line 593, in <module>
      f.write(jsonenc.encode(dump.vmsd_desc))
  TypeError: a bytes-like object is required, not 'str'

  Traceback (most recent call last):
    File "scripts/analyze-migration.py", line 601, in <module>
      f.write(jsonenc.encode(dict))
  TypeError: a bytes-like object is required, not 'str'

This happens because the file 'f' is open in binary mode while
jsonenc.encode() returns a string.

The results are human-readable files, 'desc.json' and 'state.json',
so there is no reason to use the binary mode.
