[bugfix] [RHEL/7, Fedora] Specify particular profile names rules of which should be displayed in the generated HTML guide

OpenSCAP v1.1.1 with its new way of HTML report & HTML guide changed previous way how HTML guide is generated. Previously when specifying non-existing profile, it would list all rules (rules from all profiles) in the final guide. Now it's necessary:
  [1] https://www.redhat.com/archives/open-scap-list/2014-September/msg00032.html

to specify concrete profile name, rules of which should be displayed in the HTML guide (otherwise generated guide will contain just group sections, without rules).

Therefore use 'rht-ccp' as profile name for RHEL-7 & 'common' for Fedora products.
RHEL-6 Makefile doesn't require a change, since it's still using openscap-v1.0.8 (thus the old way for generation of HTML report & guide => nothing changed here).

Tested on both of RHEL-7 & Fedora & works fine for me [*].

Please review.

Thanks, Jan.

[*] &nbsp; A careful reader might notice in the newly generated guide that there are improperly rendered sections like: &nbsp; &nbsp; ```$ sudo systemctl enable / disable ...```.
&nbsp; &nbsp; This will need fixing yet (planning to look tomorrow at that issue).
Because the guide.html is now per-profile (which is fantastic!), we should likely include the profile name in the filename.

what do you think of ```` ..... > $(OUT)/$(PROD)-ccp-guide.html```` ?
