helpers: Call rst2html directly on *nix
Initially, rst2html was called via the python interpreter which would
fail if the script was wrapped in a launcher as on NixOS.
Ideally, on *nix, binaries should be invoked directly to ensure that
shebangs work properly as is being done now.
Handle the case of windows as it doesn't do shebangs.
