packaging: avoid running bare "make install" in debian/rules
We change the "override_dh_install" target to "override_dh_auto_install"
in debian/rules (see dh_auto_install(1) for details). This is because we
do not want "make install" to be run automatically as we need the
--install-layout=deb of "setup.py install". Otherwise, files end up in
$DESTDIR/usr/local. At the moment, this is not a problem since files
installed in debian/tmp (the default location) are not packed into
binary packages (because there are debian/mercurial and
debian/mercurial-common directories). This is cleaner to avoid running
make more than needed.
