procutil: make mercurial.utils.procutil.stderr unbuffered

For most Mercurial code, it doesn’t make a difference, as the ui object flushes
stderr explicitly (after the change, we could get rid of the explicit flush).
One example where it makes a observable difference is mercurial.util.timed().
Without the patch, the time is not immediately shown on Python 3. With the
patch, it’s shown immediately on all Python versions and platforms.

from __future__ import absolute_import, print_function

import sys

for line in sys.stdin:
    if line.lower() in ("message-id: \n", "in-reply-to: \n"):
        line = line[:-2]
    print(line, end="")
