virtiofsd: Add timestamp to the log with FUSE_LOG_DEBUG level 

virtiofsd has some threads, so we see a lot of logs with debug option.
It would be useful for debugging if we can see the timestamp.

Add nano second timestamp, which got by get_clock(), to the log with
FUSE_LOG_DEBUG level if the syslog option isn't set.

The log is like as:

  # ./virtiofsd -d -o vhost_user_socket=/tmp/vhostqemu0 -o source=/tmp/share0 -o cache=auto
  ...

  [5365943125568644] [ID: 00000002] fv_queue_thread: Waiting for Queue 0 event
  [5365943125573561] [ID: 00000002] fv_queue_thread: Got queue event on Queue 0
