gctest: Avoid use of deprecated GC_dont_gc and GC_stackbottom

* tests/test.c (GC_amiga_gctest_malloc_explicitly_typed,
GC_amiga_gctest_calloc_explicitly_typed): Do not unnecessarily check
GC_dont_gc value.
* tests/test.c (check_heap_stats): Get stack base via
GC_get_stack_base() (report error if failed) instead of accessing
GC_stackbottom.
