[PATCH v2] Linux: Add missing si_code constants from Linux kernel

[Thiago Jung Bauermann]

This brings the si_codes listed in siginfo-consts.h up-to-date with
Linux v6.16's include/uapi/asm-generic/siginfo.h.

Tested on aarch64-linux-gnu and x86_64-linux-gnu.

Suggested-by: Carlos O'Donell <carlos@redhat.com>
---

Change in v2:
- Surrounded enum of SIGSYS s_codes with #ifdef __USE_GNU, as suggested
  by Carlos to fix the conform failures in signal.h and wait.h.
