[SPARC]: avoid CHILD_MAX and OPEN_MAX constants
I don't figure anyone really cares about SunOS syscall emulation, and I
certainly don't. But I'm getting rid of uses of the OPEN_MAX and CHILD_MAX
compile-time constant, and these are almost the only ones. OPEN_MAX is a
bogus constant with no meaning about anything. The RLIMIT_NOFILE resource
limit is what sysconf (_SC_OPEN_MAX) actually wants to return.
The CHILD_MAX cases weren't actually using anything I want to get rid of,
but I noticed that they are there and are wrong too. The CHILD_MAX value
is not really unlimited as a -1 return from sysconf indicates. The
RLIMIT_NPROC resource limit is what sysconf (_SC_CHILD_MAX) wants to return.
