procutil: don't allow the main 'hg' script to be treated as the Windows exe

Previously, there were a handful of errors like this:

     $ hg prefetch --repack
     (running background incremental repack)
  +  abort: %1 is not a valid Win32 application
  +  [255]

CreateProcess() doesn't append .exe when `lpApplicationName` contains a path,
and a python script isn't directly executable.
