Remove json5_generator.Writer parameters with specification None.
There are a few places where the parameter specification is None. This
is intended to indicate that this parameter has no restrictions on its
values. However, in actual JSON files, this is expressed by using an
empty dictionary '{}' instead of None. This patch changes None to '{}'
to be consistent with JSON files.
