haskell-ghc-mod: patch ghc-process.el to avoid hanging

Browse Source 
@peti I've determined that the hang which this fixes does not happen all
of the time (in fact, I've been using ghc-mod for weeks without seeing
it once).  But today it happened again, and it made me realize I had
undone this patch locally.  I'm committing it now because it fixes the
problem completely for me, and certainly cannot hurt.
