egg-info syntax wrong in epel7.spec

Hello,

with the default `epel7.spec` if I run

`pyp2rpm -o epel7 -t epel7 -b 3 -s dist/-0.1.post8.tar.gz`

in `%files -n python%{python3_pkgversion}-%{pypi_name}` I read:

`%{python3_sitelib}/-%{version}-py%{python3_version}.egg-info`

This is wrong. I should see:
`%{python3_sitelib}/-%{version}.post8-py%{python3_version}.egg-info`

It lacks of **.post8**. Now I'm fixing by hands... could you help me to modify the template in order to let pyp2rpm to write the right line?
Thank you very much

Ps: the issue is the same for fedora spec too.
