gnu: Remove python-setuptools and python2-setuptools from inputs (part 3)

This patch contains the changes where setuptools are used in an inherited
package and removing this input keeps the need for inheriting the package.

* gnu/packages/bioinformatics.scm (python2-biom-format): Remove
  python-setuptools respective python2-setuptools from [inputs],
  [native-inputs] and [propagated-inputs] in Python 2 packages inheriting from
  a Python 3 package.
* gnu/packages/python.scm (python2-pytest-mock,
  python2-oauthlib,
  python2-seaborn,
  python2-tornado,
  python2-terminado,
  python2-rauth,
  python2-anyjson,
  python2-amqp,
  python2-kombu,
  python2-billiard,
  python2-celery,
  python2-jellyfish,
  python2-binaryornot,
  python2-natsort,
  python2-graphene): Likewise.
* gnu/packages/statistics.scm (python2-statsmodels): Likewise.
