Also move system headers stdbool.h and stdint.h last to avoid them being
accidentally included.
Fixes commit b91e253f65 ("include: sof: debug: Split panic.h into
Zephyr and XTOS-specific headers") that broke `scripts/fuzz.sh` because
it stopped `sof/ipc/common.h` from accidentally getting `ipc/stream.h`
through `panic.h`.
Fixes:
```
