syscall argument sanitization for waitpid

[celinehoang177]

Sanitize waitpid syscall arguments (issue #612). Introduced a WaitpidChildSelector enum to interpret raw inputs at the entry point, ensuring special values (e.g., -1) are handled correctly before reaching core logic. This resolves bugs like #543, where -1 was incorrectly passed to get_cage().
