package/python-setuptools: drop bogus select on missign symbol

Commit 3b2913552e (package/python-setuptools: add missing dependency on
host-python-wheel) adding the select of the runtime, as a last-minute
fixup.

However, there is no target python-wheel package; it is a host-only
package, leading to sainty-check failures:

    $ make check-symbol
    package/python-setuptools/Config.in:5: BR2_PACKAGE_PYTHON_WHEEL referenced but not defined

Srop the select. If there was a rationale for actually having
python-wheel on the target, it's going to need a bit more.
