spec: Stricten a dependency on DNF libraries in plugin subpackages

ELF plugins of dnf5-plugins and dnf5-plugin-automatic subpackages link
to libdnf and libdnf-cli libraries. Because the libraries come from
the same source package, it is desired to pin the plugin subpackages
to same release of the libraries subpackages.

This was hinted by rpminspect and already partially implemented in
commit 97cdbe5 ("Add explicit package
version for libdnf5-cli").
