Update the osbuild/images to the version which introduces "dot notation" for distro release versions. - Replace all uses of distroregistry by distrofactory. - Delete local version of reporegistry and use the one from the osbuild/images. - Weldr: unify `createWeldrAPI()` and `createWeldrAPI2()` into a single `createTestWeldrAPI()` function`. - store/fixture: rework fixtures to allow overriding the host distro name and host architecture name. A cleanup function to restore the host distro and arch names is always part of the fixture struct. - Delete `distro_mock` package, since it is no longer used. - Bump the required version of osbuild to 98, because the OSCAP customization is using the 'compress_results' stage option, which is not available in older versions of osbuild.
