While debugging another problem, I found a couple of issues with system() on FreeBSD:

 * follow-freq(0) doesn't appear to work, so /dev/klog gets ignored outright
 * Even with follow-freq(1), we never read from /dev/klog, because stat() will report its size to be 0, so we never end up reading from it.

The second is easy to fix, adding an || !S_ISREG(st.st_mode) to the appropriate condition in log_reader_io_follow_file() does the right thing.
