bug#37797: [PATCH 1/1] emacs-module-tests: fix VPATH builds

[Rob Browning]

---

 I'm not sure it's a desirable approach, but this does allow the
 emacs-module-tests to succeed when run from an out-of-tree build,
 e.g.

    mkdir build && cd build && ../configure && make check

 The bzr tests are still broken in that situation (if the tools are
 installed), but for the moment, that's not critical here.

 Hope this helps.
