COMPOSER-2068

To avoid incompatibility between older image-info and latest osbuild

The RHEL nightly composes still contain old osbuild-composer version,
which does not have an explicit dependency on osbuild-depsolve-dnf
package.

As a result, running the latest upstream base_tests.sh on RHEL nightly
composes fails due to osbuild-depsolve-dnf not being installed.

Workaround this in the test case by explicitly installing the
osbuild-depsolve-dnf package in case the osbuild-composer version is
lower than the one which has an explicit dependency on
osbuild-depsolve-dnf.
