update ptrace.h to latest from glibc

Update libc/sysdeps/linux/common/sys/ptrace.h to latest from glibc's
sysdeps/unix/sysv/linux/sys/ptrace.h.

This adds definitions for operations:
 - PTRACE_GETREGSET
 - PTRACE_SETREGSET
 - PTRACE_SEIZE
 - PTRACE_INTERRUPT
 - PTRACE_LISTEN

And adds flags:
 - PTRACE_SEIZE_DEVEL

And adds event codes:
 - PTRACE_EVENT_SECCOMP

This is to allow access to the generic interface for accessing
architecture specific regsets using the corresponding NT_* types,
required for new Linux kernel architecture ports.
