mds: use mds_stamp for mksnap

Use the server timestamp for the snapshot timestamp.  This could arguably
be the client timestamp, but I think snapshot creation times are a bit
more important to have accurate timestamps on, and this should not be
something that existing client apps will strongly depend on.
