Provide fallback definitions for PTRACE_GET_SYSCALL_INFO API. Add very basic PTRACE_GET_SYSCALL_INFO support in the parser of ptrace syscall. * ptrace.h: Include <stdint.h>. [!PTRACE_GET_SYSCALL_INFO] (PTRACE_GET_SYSCALL_INFO, PTRACE_SYSCALL_INFO_NONE, PTRACE_SYSCALL_INFO_ENTRY, PTRACE_SYSCALL_INFO_EXIT, PTRACE_SYSCALL_INFO_SECCOMP, struct ptrace_syscall_info): Define. * xlat/ptrace_cmds.in: Add PTRACE_GET_SYSCALL_INFO. * process.c (SYS_FUNC(ptrace)): Handle it.
