torture/smb2: delayed timestamp updates test: more then one write

Verify a close updates the write-time for subsequent writes after an initial
write started the delayed update logic.

This covers a scenario that will become relevant with the two subsequent
commits. The next commit:

  smbd: let mark_file_modified() always call trigger_write_time_update()

ensures that trigger_write_time_update() is not only called for the first write
on a file. Without that preaparatory change, the second commit:

  smbd: let delayed update handler also update on-disk timestamps

alone would cause this test to fail.
