Bug 1554340

Description of problem:
When using katello-certs-check to verify a correct certificate, key, and CA, a success message is given if there is no EOL/EOM in the end of the certificate file. Installing this cert will succeed, and the web console for Satellite will show a valid, passing cert, but the subsequently-generated katello-ca-consumer certificate RPM will have a script error that causes clients to not be able to register and existing clients will get SSL errors.

Version-Release number of selected component (if applicable):
6.2.14 on RHEL 7.4

How reproducible:
Install certificate with no EOL/EOM using satellite-installer --scenario satellite -c <cert> -k <key> -r <csr> -b <ca> --certs-update-server --certs-update-server-ca --certs-update-all 
(From https://access.redhat.com/documentation/en-us/red_hat_satellite/6.2/html-single/installation_guide/index#configuring_satellite_server_with_custom_server_certificate)

Steps to Reproduce:
1. Generate CSR/key
2. Receive cert with no EOL/EOM (or modify cert to not have one)
3. Install cert with above command.

Actual results:
Cert passes validation checks with katello-certs-check and satellite-installer, and shows as valid in web console, but has script errors in the katello-ca-consumer RPM.

Expected results:
As above, but no errors in the RPM.

Additional info:
Script that generates RPM should have sanity checking for this. See RHN report: 02049269
