lang/python/egg.mk should not make py-setuptools an installation dependency

[Oliver Gould <ver%olix0r.net@localhost>]

Hola-

I've been poking around lang/python/*.mk, and I noticed that egg.mk
contains:

> DEPENDS+=     ${PYPKGPREFIX}-setuptools>=0.6c9:../../devel/py-setuptools

I believe that this should be BUILD_DEPENDS rather than DEPENDS.
Setuptools is a development library typically included from the package's
setup.py script used during package-build; as such, it should not be
required on a production system.

Is there any reason that setuptools is needed at/after install-time?
