Subject: Linux: Include <linux/sockios.h> in <bits/socket.h> under __USE_MISC

Historically, <asm/socket.h> (which is included from <bits/socket.h>)
provided ioctl operations for sockets.  User code accessed them
through <sys/socket.h>.  The kernel UAPI headers have removed these
definitions in favor of <linux/sockios.h>.  This commit makes them
available via <sys/socket.h> again.
