Jeremy Fleischman 0567c10d68 When formatting a requirement, only lowercase its name. ...

This fixes https://github.com/pypa/pipenv/issues/2113.

This bug was introduced in
<https://github.com/jazzband/pip-tools/pull/452> as a band-aid fix to
<https://github.com/jazzband/pip-tools/issues/431>. Pipenv then copied
that code in <https://github.com/pypa/pipenv/commit/2553ebcbf7e2574c997a9164234e0adf077ffcac#diff-b56b95ccea8595a0f6f24ea753842976>, and inherited this latent bug.

Maybe the right fix is for pypa/packaging to lowercase the name? There's
a comment here
<https://github.com/pypa/packaging/blob/16.8/packaging/requirements.py#L86>
about normalizing the requirement's name, which might be what this is
referring to.

To test this, I invented a new, very simple python package called
`depends-on-marked-package`. The setup.py for this package is just:

```python
import setuptools

setuptools.setup(
    name="depends-on-marked-package",
    version="0.0.1",
    packages=setuptools.find_packages(),
    install_requires=['pytz; platform_python_implementation=="CPython"'],
)
```

This is a simplified version of gevent's setup.py's install_requires upon greenlet.
