(maint) Update Windows 10 platform names
(maint) Update Windows 10 platform names

 - Previous convention for Windows platforms is to always end in a -32
   or -64.  There are some tests that rely on this naming scheme to
   properly identify a 32-bit or 64-bit OS.

   For instance, a Puppet acceptance test relies on that convention when
   detecting the location of binaries per:

   https://github.com/puppetlabs/puppet/blob/master/acceptance/tests/ensure_puppet-agent_paths.rb#L140-L143
