fix equal? between an array and a non-array

Browse source 
OK let's try again. While the thanks go to Daniel Llorens del Río for
the tip, the blame continues going to me :)

* test-suite/Makefile.am:
* test-suite/tests/arrays.test: Add a test.

* libguile/array-map.c (raeql): Handle a few 0-dimensional cases. If the
  shapes of the arrays don't match, just return #f instead of raising
  an error.
