Subject: [PATCH v2] tools/nolibc: Use linux/wait.h rather than duplicating
 it

Linux defines a few custom flags for waitpid() which aren't currently
provided by nolibc, make them available to nolibc based programs by just
including linux/wait.h where they are defined instead of defining our
own copy of the flags.

Changes in v2:
- Use linux/wait.h rather than defining things locally.
- Link to v1: https://lore.kernel.org/r/20231020-nolibc-waitpid-flags-v1-1-8137072dae14@kernel.org
