Fixed 'sha'-using repos by teaching one more place to normalize check…

…sum-type.

Test coverage is:
```
$ export FIPS_WORKFLOW=true
$ export CDN_CLIENT_CERT=`cat /PATH/TO/YOUR/cdn.crt`
$ export CDN_CLIENT_KEY=`cat /PATH/TO/YOUR/cdn.key`
$ export CDN_CA_CERT=`cat /PATH/TO/YOUR/redhat-uep.pem`
$ pulpcore-manager test pulp_rpm.tests.functional.api.test_fips_workflow.FipsRemotesTestCase.test_077_cdn_redhat_com_content_dist_rhel_server_6_6_6_x86_64_os
```
