silence some "defined but not used" warnings

[Bruno Haible]

In order to silence these warnings

../../gllib/get-rusage-data.c:354:1: warning: 'get_rusage_data_via_iterator' 
defined but not used [-Wunused-function]
../../gllib/hamt.c:201:1: warning: 'init_element' defined but not used 
[-Wunused-function]
../../gltests/../gllib/stack.h:75:24: warning: 'stack_current_base' defined but 
not used [-Wunused-function]

I'm making use of _GL_ATTRIBUTE_MAYBE_UNUSED.
