contrib: drop python2.7 from the Windows dependency install script

While we aren't quite ready to drop py27 yet, the MS compiler is no longer
available from MS (there is a copy on github if it's really needed), and that
causes the script to fail.

Differential Revision: https://phab.mercurial-scm.org/D11273

#!/usr/bin/env python3
#
# This is literally `cat` but in python, one char at a time.

# see sigpipe-remote.py for details.
