svn commit: r263343 - stable/9/lib/libprocstat

Log:
  Merge r262690 from head to stable/9:
  
    When querying a process's umask via sysctl in libprocstat(), don't
    print a warning if EPERM is returned as this is an expected failure
    mode rather than error -- similar to current handling of ESRCH.
    This makes the output of 'procstat -as' vastly more palatable.
