The python2-tqdm package requires Python 3.

How reproducible: always

Steps to Reproduce:
1. repoquery --requires python2-tqdm
2. observe the output:

```
/usr/bin/python3.6
python(abi) = 2.7
```

Installing python2-tqdm will bring in Python 3.

Expected results: only Python 2 stack required.


Additional info:

According to example instructions here: https://python-rpm-porting.readthedocs.io/en/latest/tools.html

The /usr/bin/tqdm should be provided by "default" Python stack, so only the python2-tqdm should be the one with /usr/bin/tqdm, and python3-tqdm should have /usr/bin/tqdm-3.

But the current situation is that both python2-tqdm and python3-tqdm install the binary to the same location.
And moreover, the /usr/bin/tqdm is always of the Python 3 version.
