ticket #199 - update STIG partitioning

this PR resolves ticket #199

The RHEL7 STIG requirements do not mandate the legacy partitioning models of /home, /var, etc.
Updating the XCCDF profiles to reflect. Chose to update in common as it's unlikely other RHEL7 profiles will require legacy partitioning.
