    Fix out-of-source ‘make check’ emacs-module-tests
    
    Problem reported by Koki Fukuda in:
    https://lists.gnu.org/r/emacs-devel/2020-07/msg00169.html
    * test/Makefile.in (MODULE_CFLAGS):
    Include from the same directories included from in ../src.
    * test/src/emacs-module-tests.el (module/describe-function-1):
    Strip path to source directory.
