Add initial rpminspect role
    
    - Issue wrapping into ansible - issue upstream
    - rpminspect segfault in compare mode
    
    Two use cases, by default w/o check_previous_build enabled
    rpminspect do a sanity check of the built package.
    With check_previous_build enabled, the role fetch the latest build
    on koji and rpminspect will perform the before and after build
    compare too.
