depsolve: filter out conflicting provider. BZ 1480065
    
    When there are multiple providers available for a requirement, yum would
    happily pick the one that the requiring package also has a "Conflicts:"
    on (via another virtual provide), failing to resolve the transaction.
    
    Example:
    - foo requires bar and conflicts my-bar
    - bax provides bar
    - bay provides bar, my-bar
    
    Yum might decide to pick bay, only to fail due to the conflict with foo
    later in the process.
    
    This commit fixes that by dropping such a provider from the candidate
    list when depsolving.
