Use vfs_timestamp() instead of getnanotime() to set timestamps. This

fixee incoherency of pipe timestamps relative to file timestamps in
the usual case where getnanotime() is not used for the latter.  (File
and pipe timestamps are still incoherent relative to real time unless
the vfs_timestamp_precision sysctl is set to 2 or 3).
