util: simplify pipefilter and avoid subprocess race

The subprocess module is not thread safe. Spawning a thread to read
the output leads to exceptions like this when Mercurial exits:

  Exception exceptions.TypeError: TypeError("'NoneType' object is not
  callable",) in <bound method Popen.__del__ of <subprocess.Popen
  object at 0x9ed0dcc>> ignored

The bug is already reported in the Python bug tracker:
