Let mmap allocate a block of memory that's wide enough to use with MADV_WIPEONFORK, madvise granularity is the current system page size (using a static buffer of mem.page_size bytes would be wrong, that's the minimum page size). As a result, we don't zero some random chunk of memory every time we fork the process. Fixes ziglang#7609
