Use hatch version, shorter name, add obsoletes (#265)

* Use `hatch version` instead of packit default

By default packit creates rpms with version which can be older
than packages already released in Fedora repositories. We need to
use `hatch version` to at least bump the micro version.

* Use shorter names for latest packages from `main`

* We need to obsolete the dropped `python3-fmf` package
