suse platform: read /etc/SuSE-release only once.

doing it twice is (slightly) inefficient and complicates the tests
[OHAI-339] distinguish openSUSE from SUSE Linux Enterprise

- platform_family: stays "suse" for both
- platform: SLE, being the more stable platform,
                 gets to keep platform "suse"
            openSUSE is now platform "opensuse"
- platform_version: is "MAJOR.MINOR" even for SLE which officially is
                    versioned as "MAJOR [SP MINOR]"

I considered to change the platform only for *future* openSUSE
versions (12.3 or later) but decided against it: "suse" >= 12 would
then conflict with a future SLE 12 (scheduled for 2014).
Disable root_group on Windows

Fixes OHAI-490: http://tickets.opscode.com/browse/OHAI-490

Implementation of root_group for windows has been found to have poor
performance when the host is joined to an AD domain. Opting to disable
on Windows since large changes will be required for a performant
implementation.

Cherry-picked from master for 6-stable.
