Fix indentation for the distributions key.

After some searching, it turns out that the `distributions` key was put within the `on` key (which makes no sense) so that any changes to it would not be detected, since the value of `distributions` was defaulting to just "sdist". Thanks to this guy: JonathonReinhart/scuba#71 (comment)
