Further cleanups to use of timestamps in NFS:

- Use NFSD_MONOSEC (which maps to time_uptime) instead of the seconds
  portion of wall-time stamps to manage timeouts on events.
- Remove unused nd_starttime from the per-request structure in the new
  NFS server.
- Use nanotime() for the modification time on a delegation to get as
  precise a time as possible.
- Use time_second instead of extracting the second from a call to
  getmicrotime().
