Use Autoconf to generate the test module Makefile

This makes it easier to pass compilation flags around.

* configure.ac: Also build test module Makefile.

* test/data/emacs-module/Makefile.in: New makefile template.

* test/Makefile.in ($(test_module)): No longer necessary to pass
@MODULES_SUFFIX@ around.

* .gitignore: Test module Makefile can now be ignored.
