windows: bash.exe path

Path for bash process in Windows 10 WSL (nodejs code):

process.env.hasOwnProperty('PROCESSOR_ARCHITEW6432') 
  ? "C:\\Windows\\sysnative\\bash.exe" 
  : "C:\\Windows\\System32\\bash.exe";

When using shell (cmd or powershell), simple bash call seems to do the trick, no need to use full path.

bash.exe is deprecated, aiming to support wsl.exe in next releases
