child_process: fix switches for alternative shells on Windows

On Windows, normalizeSpawnArguments set "/d /s /c" for any shells.
It cause exec and other methods are limited to cmd.exe as a shell.

Powershell and git-bash are often used instead of cmd.exe,
and they can recieve "-c" switch like unix shells.
So normalizeSpawnArguments is changed to set "/d /s /c" for cmd.exe,
and "-c" for others.
