syslogd: Fix buffering of partial klog lines

 When a /dev/klog read ends without a newline, the remaining data
is buffered for the next read. The code mistakenly copied the data
into linebuf instead of klog_linebuf, breaking reconstruction of
split log messages.

Found and fixed by nonaka@ and Kenichi Suzuki at IIJ.

syslogd: Preserve full partial klog line when buffering

 Buffer incomplete /dev/klog lines from the start of the original
line instead of the parse position. Otherwise, split messages
lose the BSD syslog priority prefix when reconstructed.

Fixed by Kenichi Suzuki at IIJ.
