pkg/system: move IsWindowsClient to pkg/parsers/operatingsystem

Browse source 
This function was only used in a single place, and pkg/parsers/operatingsystem
already copied the `verNTWorkstation` const, so we might as well move this function
there as well to "unclutter" pkg/system.

The function had no external users, so not adding an alias / stub.
