doc/Makefile: detect the right name for rst2man and rst2html

docutils uses the .py extension on the commands, and so do their installer.
Distribution packages might strip the .py, but the official name should work too.

SOURCES=$(wildcard *.[0-9].txt)
MAN=$(SOURCES:%.txt=%)
HTML=$(SOURCES:%.txt=%.html)
PREFIX=/usr/local
MANDIR=$(PREFIX)/share/man
INSTALL=install -c -m 644
PYTHON=python
RST2HTML=$(shell which rst2html 2> /dev/null || which rst2html.py)
RST2MAN=$(shell which rst2man 2> /dev/null || which rst2man.py)
