Log Message:
fix a simonb-timecounters regression.
the precision of getnanotime() is not suitable for file timestamps.
esp. when it's nfs-exported.

- introduce vfs_timestamp().
  (the name is from freebsd.  currently merely a wrapper of nanotime())
- for ufs-like filesystems, use it rather than getnanotime().

XXX check other filesystems.
