Closes #385

How did you implement it:

Modified the existing scan/redhat.go and scan/redhat_test.go source to identify Oracle Linux. Also updated report/util.go and report/writer.go to reference the correct URL for the Oracle Linux CVE and Errata information.

Scan an Oracle Linux Docker image. You can scan oraclelinux:5, oraclelinux:6 and oraclelinux:7. The last image/tag is also oraclelinux:latest

Many thanks.

@kotakanbe I can squash them, or you can use GitHub's "Squash and Merge" button, which does it automatically for both of us. :)

To be honest, I just knew it now :)
Thanks!

Yeah, I get lazy these days because I know GitHub can squash things on merge. :)
