Various pages: Remove unused <sys/ipc.h> (and <sys/types.h>)

In b0b19983d9a2001ce94b908a99f4c05a50fd47ee we removed
<sys/types.h>.  For the same reasons there, remove now <sys/ipc.h>
from many pages.

If someone wonders why <sys/ipc.h> was needed, the reason was to
get all the definitions of IPC_* constants.  However, that header
is now included by <sys/msg.h>, so it's not needed anymore to
explicitly include it.  Quoting POSIX: "In addition, the
<sys/msg.h> header shall include the <sys/ipc.h> header."

There were some remaining cases where I forgot to remove
<sys/types.h>; remove them now too.
