realloc-gnu: avoid glibc MALLOC_CHECK_ issue

Browse Source 
* tests/test-realloc-gnu.c (main): if MALLOC_CHECK_ env var
is set then don't check ENOMEM is returned from realloc().
See https://sourceware.org/bugzilla/show_bug.cgi?id=27870
Note it doesn't suffice to unsetenv() this var within the program,
as the hooks have already been set up at that stage.
