Add explicit package version for libdnf5-cli

The change was suggested by rpminspect. See the description bellow.

Add the indicated explicit Requires to the spec file for the named
subpackage. Subpackages depending on shared libraries in another
subpackage must carry an explicit
'Requires: SUBPACKAGE_NAME = %{version}-%{release}' in the spec file.
VERIFY Subpackage dnf5 on s390x carries
'Requires: libdnf-cli.so.1()(64bit)' which comes from subpackage
libdnf5-cli but does not carry an explicit package version requirement.
Please add 'Requires: libdnf5-cli = %{version}-%{release}' to the spec
file to avoid the need to test interoperability between various
combinations of old and new subpackages.
