libpayload/libc: Fix memset/sizeof usage
Since r is a pointer, memset(r, 0, sizeof(r)) would only zero the first
4 (or 8) bytes of the newly allocated struct align_region_t.
An alternative to this patch would be to use calloc, or introduce a new
zalloc (zeroed allocation; a single-element calloc) and use that.
