MFP4: Change 109654

Add two linprocfs entries for Linux IPC:

/proc/sys/kernel/msgmni -> kern.ipc.msgmni
/proc/sys/kernel/sem -> kern.ipc.semmsl

					kern.ipc.semmns
					kern.ipc.semopm
					kern.ipc.semmni

This fixes msgget03 and semget05 from Linux Test Project (LTP) test suite.
msgctl08 and msgctl09 also use /proc/sys/kernel/msgmni but another fix is
required from p4 (Change 110179).
