patch 9.1.1948: Windows: Vim adds current directory to search path

Browse Source 
Problem:  Windows: Vim always adds the current directory to search path.
          This should only happen when using cmd.exe as 'shell'. For
          example, powershell won't run binaries from the current
          directory.
Solution: Only add current directory to system path, when using cmd.exe
          as 'shell'.
