Inline test module Makefile into main test Makefile

The test/data/emacs-module/Makefile only built a single target, and
inlining it into test/Makefile simplifies dependency tracking and
reduces code duplication.

* configure.ac: Don't build test/data/emacs-module/Makefile.

* Makefile.in ($(test_module)): Inline compilation.
(clean): Also clean test module outputs.
