makefile: use Python 3 by default (BC)
This change is long overdue IMO.
.. bc::
Makefile now uses `python3` instead of `python` by default on
non-Windows platforms. This means Mercurial will be built and
run with Python 3 instead of Python 2.7 by default.
To continue using Python 2, set the PYTHON variable. e.g.
`make install PYTHON=python2.7`.
