    Run a build with with an invalid 'build_require' module.
    I.e.: required module is picked in such a way,
    that it is not tagged according to the the base module (platform) requirements,
    see platform's modulemd file and its 'koji_tag_with_modules' attribute
    (e.g.: platform: el-8.1.0 --> rhel-8.1.0-modules-build).

    Koji resolver is expected to not be able to satisfy this build requirement
    and hence fail the build.

    Assert that:
    * the module build hasn't been accepted by MBS:
      rhpkg utility returns something else than 0
    * "Cannot find any module build..." found on STDERR

    If assert fails:
    * cancel all triggered module builds.
