    rhel: Check that after casting to mappingFile we have a usable mapper

    Currently it is possible that if the repo2cpe_mapping_url or the
    repo2cpe_mapping_file (or indeed if the endpoint is down) that we will
    panic as the mappingFile will cast to a nil. This will check for a nil
    mapper before it gets accessed and error out. This is also an issue
    for name2repos_mapping_url and name2repos_mapping_file used by RHCC
    scanner.

What is funny to me is that this is apparently an Alpine image, but the error indicates that it's related to rhel-specific code.

Because we don't know anything about the image when we index it, all the (configured) scanners are run on every layer, hence why the rhel specific scanning is running.

The PR that holds the commit mentioned was to avert a panic in the above situation and instead surface. Since then we've changed the instantiation of a number of components and this should be non-issue going forward (quay/claircore#867) as the ingesting of the files should be a lot more infrequent.

This should be fixed in 4.7
