Fix __sysctl() to return the proper value to the caller, to match 

documented behavior.  sysctl(3) is documented to return 0 on success,
-1 on failure.  The previous behavior was to return -1 on failure
and the number of bytes copied back down to user space.
Fixes part of PR #1999, from Kevin M. Lahey <kml@nas.nasa.gov>
