subpackage requirement should be versioned

The setuptools entry point in /usr/bin/rpmdeplint is going to have its
own versioned requirement embedded anyway, so to satisfy that we need
them to stay in sync.

Plus if somebody says "dnf upgrade rpmdeplint" they probably want the
actual Python module upgraded too. See Fedora bug 1462047.
