Replace 0600 in shmget(2) call with symbolic constants.

Browse Source 
Inspired by Rich Alderson's MacOS 10.6.8 changes.
He used IPC_CREAT+IPC_PRIVATE+IPC_R+IPC_W.
However, IPC_PRIVATE is a special value for the key argument, not shmflg.
Furthermore, adding IPC_CREAT to the flags when the key is IPC_PRIVATE
seems unnecessary but should not harm.

See http://pubs.opengroup.org/onlinepubs/9699919799/functions/shmget.html
for the "IEEE Std 1003.1-2008, 2016 Edition" version of shmget(2).
