s4/torture: Parameterize output in LOCK tests based off server support

Two new torture parameters:

* smbexit_pdu_support: if the Server supports the Exit command

* range_not_locked_on_file_close: whether the server returns the
  NT_STATUS_RANGE_NOT_LOCKED error when a file is closed which has a
  pending lock request.  Windows returns this error, though per the
  spec, this error should only be returned to an unlock request.
