migration: Set downtime_start even for postcopy
Postcopy calculates its downtime separately. It always sets
MigrationState.downtime properly, but not MigrationState.downtime_start.
Make postcopy do the same as other modes on properly recording the
timestamp when the VM is going to be stopped. Drop the temporary variable
in postcopy_start() along the way.
