Bash remediation for sshd_allow_only_protocol2
[RHEL/7] Drop service_haldaemon_disabled XCCDF rule from RHEL-7 content.
         HAL daemon has been removed in Fedora-16:
           [1] https://ask.fedoraproject.org/en/question/8747/hal-daemon-gone-or-not/
           [2] http://fedoraproject.org/wiki/Features/HalRemoval#Release_Notes

         and replaced / obsoleted by udisks / upower, as well as libudev for device
         discovery (the service doesn't exist anymore in RHEL-7 => no point the recommendation
         to disable it to be present there).
