[PATCH] [Fedora] Add ntp_remote_server OVAL check [Fedora] Add new system/settings section to guide [Fedora] Include disable prelink rule into system settings

[Jan Lieskovsky]

[Fedora] Add OVAL check to test if there's is remote NTP server configured for time data
[Fedora] Add system settings section for the guide (to track system wide hardening configurations)
[Fedora] Include disable prelink rule and OVAL check for it

This patch adds the following:
* provide OVAL check to test if /etc/ntp.conf contains 'server' entry
  (based on RHEL6's one, just slightly modified),
* introduce new system/settings section for the guide (to track
  universal system wide configurations / principles, which wouldn't
  fall into other more specific category),
* include 'disable_prelink' rule as a representative of such a
  system settings rule. Add OVAL check for it (based on RHEL6's one).

Please review.

Thank you && Regards, Jan.
