Correct the formulas for System V IPC parameters SEMMNI and SEMMNS in docs.
In runtime.sgml, the old formulas for calculating the reasonable values of SEMMNI and SEMMNS were incorrect. They have forgotten to count the number of semaphores which both the checkpointer process (introduced in 9.2) and the background worker processes (introduced in 9.3) need. This commit fixes those formulas so that they count the number of semaphores which the checkpointer process and the background worker processes need. Report and patch by Kyotaro Horiguchi. Only the patch for 9.3 was modified by me. Back-patch to 9.2 where the checkpointer process was added and the number of needed semaphores was increased.
