Huge thanks to @xTibor for both discovering that this was still an issue, and also providing information with how to fix it

Turns out, it's just redox not having a NULL pointer here. Linux does.

This undos a workaround. Jeremy moved the ralloc stuff to platform and suddenly this seems to work again. I don't know what is different from when I tried this before and now, but I don't really care

Add cargo fmt script

 - Add aarch64 support
   - crt0 - add support to _start
   - platform - aarch64 does not have the open syscall. Instead most
     libc implementations use openat() with AT_FDCWD
 - Use sc instead of syscall. sc is the maintained fork of syscall.
