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.
