This deals with a reported issue when running and building containers
on a CentOS host system.

Fixed various typos in version checking when running on a CentOS system.
Added logic for differences between point releases (6.5) and rolling (6).
Added version detection logic when running on RHEL systems as well.
Fixed cpe detection string (CentOS is not adhering to their own registration).
Added logic to disable the pam_loginuid.so binary in containers.
