[BUG] Some Org mode files require org-macs.el more than once

[Niall Dooley]

Reviewing some Org files I noted the following files require org-macs.el more
than once:

- ob.el
- ob-python.el
- org-fold.el

There are likely others too.

The additional require seems redundant to my ignorant self.  I appreciate this
should cause no issue but is there a reason why such lines are duplicated?
I've indicated this as a BUG in the subject line so forgive me if that is an
inaccurate characterisation.
