malloc-gnu-tests: pacify -Walloc-size-larger-than

* tests/test-malloc-gnu.c (main):
* tests/test-realloc-gnu.c (main): Hide true intentions from GCC,
to prevent diagnostics like “warning: argument 1 value
‘9223372036854775808’ exceeds maximum object size
9223372036854775807 [-Walloc-size-larger-than=]”.

        safe-alloc: fix pointer implementation
        The old implementation assumed that all pointers use the same
        internal representation, but the C standard doesn’t guarantee
