Subject: [PATCH] Makefile.am: use PYTHON when invoking psl-make-dafsa

In an environment where only Python 3 is installed, configure.ac finds and sets
PYTHON=python3 correctly but src/psl-make-dafsa is called directly, so the hashbang of
`#!/usr/bin/env python` is used which doesn't exist.

Fix this by explicitly running $(PYTHON) when using the tool.
