[CRIU] [PATCH] pycriu: images: pb2dict: preserve fields order with "pretty" option

[Ruslan Kuprieiev]

Using collections.OrderedDict allows us to keep fields in the
same order as they appear in corresponding proto files, which
helps to impove readability. In non-pretty mode we still use
regular dict.
