(#11511) Split lsb facts into multiple files

If a fact is stored in a file that does not follow the convention
$factname.rb we may encounter ordering and recursion issues as seen in
bugreport #11511. The concrete example was

- flush clears all facts
- load_all is triggered to reload facts
- inside an .rb file we query the operatingsystem fact directly
  (say outside a Facter.add block)
- the operatingsystem fact has a suitable resolver for linux which
  wants to query the lsbdistid fact, which is (apperently) not yet
  loaded (this might not even be predictable)
- the loader doesnt find a lsbdistid.rb file so it triggers load_all
  (remember: we are still trying to get a value for operatingsystem)
- the load_all does load other files (like processor.rb) that want to
  query the architecture fact directly (outside a Facter.add block)
- the architecture fact is dependent on the operatingsystem fact, we are
  currently trying to resolve -> boom: recursion

This commit implements one possible fix: Split the lsb facts into
differnet files so the loader finds them. We therefore dont have to run
load_all in the middle of a fact resolution.
Update rpm spec file

This commit updates the rpm spec file to change
the ruby dependencies to version 1.8.5. It also
removes any conditionals for ruby abi, because
we can now assume ruby abi present. The
dependency on ruby is bumped to version 1.8.5,
as we can also assume this ruby version, given
that el4 is EOL. The facter version is bumped
to 1.6.8 to reflect the latest released version.
Finally, this commit removes the manual noarch
build setting, as facter is now arch-specific
because of its dependency on dmidecode.

(#12864) Windows: get primary DNS from registry

Windows does not expose the host's primary DNS suffix via WMI, only the
registry. This commit adds a registry helper class and will retrieve the
primary DNS suffix from the registry. In the case the primary DNS suffix
does not exist or is empty, the domain fact will fall back to using WMI
for any connection-specific DNS suffix.
(#11511) Correct lsbrelease specfile filename

All spec files should follow the convention foo_spec.rb. Rename
spec/unit/lsbrelease.rb to spec/unit/lsbrelease_spec.rb.

Wrap dmidecode/pciutils in ifarch block

This commit wraps the requirement of dmidecode
and pciutils in an ifarch block, because these
packages are not available on all arches.
