If there are markers specified in requirements.txt they are not currently transferred to Pipfile while generating it. This commit adds markers to Pipfile as defined in requirements.txt
I generated this patch with:
```
$ pip install -t . tomlkit==0.12.3 --upgrade
$ rm -rf tomlkit-0.12.3.dist-info
```
from pipenv/vendor folder.
Then seearch and replace "from tomlkit" with "from
pipenv.vendor.tomlkit", and restore the LICENSE file that got removed
for some reason.
Otherwise using pipenv with a Pipfile the defaults a source without a
name causes a KeyError like:
```

* Refactor this path logic to file url bug and re-use relative pathing logic.
* Handle case where the drive letter is different and so relative path may not be possible
* Add news fragment
