(FACT-567) Restore windows dependencies during gem packaging

Restored windows dependencies during gem packaging. With this change, the gem spec contains the correct info for both x86 and x64:

x86
-----

<pre>
$ gem specification --ruby pkg/facter-2.0.2.134-x86-mingw32.gem
...
   if s.respond_to? :specification_version then
    s.specification_version = 4

    if Gem::Version.new(Gem::VERSION) >= Gem::Version.new('1.2.0') then
      s.add_runtime_dependency(%q&lt;ffi>, ["~> 1.9.3"])
      s.add_runtime_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
      s.add_runtime_dependency(%q&lt;windows-pr>, ["~> 1.2"])
      s.add_runtime_dependency(%q&lt;win32-security>, [">= 0.2.0"])
      s.add_runtime_dependency(%q&lt;win32console>, ["~> 1.3.2"])
    else
      s.add_dependency(%q&lt;ffi>, ["~> 1.9.3"])
      s.add_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
      s.add_dependency(%q&lt;windows-pr>, ["~> 1.2"])
      s.add_dependency(%q&lt;win32-security>, [">= 0.2.0"])
      s.add_dependency(%q&lt;win32console>, ["~> 1.3.2"])
    end
  else
    s.add_dependency(%q&lt;ffi>, ["~> 1.9.3"])
    s.add_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
    s.add_dependency(%q&lt;windows-pr>, ["~> 1.2"])
    s.add_dependency(%q&lt;win32-security>, [">= 0.2.0"])
    s.add_dependency(%q&lt;win32console>, ["~> 1.3.2"])
  end
</pre>

x64
-----

<pre>
$ gem specification --ruby pkg/facter-2.0.2.134-x64-mingw32.gem
...
  if s.respond_to? :specification_version then
    s.specification_version = 4

    if Gem::Version.new(Gem::VERSION) >= Gem::Version.new('1.2.0') then
      s.add_runtime_dependency(%q&lt;ffi>, ["~> 1.9.3"])
      s.add_runtime_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
      s.add_runtime_dependency(%q&lt;windows-pr>, ["~> 1.2"])
      s.add_runtime_dependency(%q&lt;win32-security>, [">= 0.2.0"])
    else
      s.add_dependency(%q&lt;ffi>, ["~> 1.9.3"])
      s.add_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
      s.add_dependency(%q&lt;windows-pr>, ["~> 1.2"])
      s.add_dependency(%q&lt;win32-security>, [">= 0.2.0"])
    end
  else
    s.add_dependency(%q&lt;ffi>, ["~> 1.9.3"])
    s.add_dependency(%q&lt;win32-dir>, ["~> 0.4.8"])
    s.add_dependency(%q&lt;windows-pr>, ["~> 1.2"])
    s.add_dependency(%q&lt;win32-security>, [">= 0.2.0"])
  end
</pre>

 Note how win32console is only a dependency for the x86 gem, but not x64.
Why was win32-security not also bumped here?
