Update the kernel headers to match external/kernel-headers.

Note that the Linux kernel handed over responsibility for most of the
socket constants to glibc some time ago. Someone had updated our
external/kernel-headers file but not regenerated the bionic headers,
so this change copies the missing stuff from the old bionic <linux/socket.h>
into <sys/socket.h>. This is what glibc does.

I've hacked a few of the other files to #include <sys/socket.h> for
backward compatibility, but even so this requires numerous other
changes to switch people over from direct inclusion of <linux/...> headers.
