[Open-scap] Including default syntax for --report & --results

[Shawn Wells]

Would it be possible to create a "default" file name syntax when
openscap receives empty --report & --results arguments?

Something like...
oscap xccdf eval --profile foo --results --report content.xml

Would generate...
`hostname`-`date +%F:%R:%S`-{results report}.xml

aka
ssg-rhel5-dev-2014-11-13:14:43:56-report.xml

If I generate a patch for this functionality, what branch would I submit
a PR against?
