reduce: costfuzz reducer does not print SELECT statements

[mgartner]

I tried reducing this costfuzz failure with ./bin/reduce -binary ./cockroach -chunk 15 -costfuzz -file failure.log -v, and it was reduced to three SQL statements with the costfuzz SELECT queries missing. The SELECT queries should be printed, like they are for TLP reductions.

CREATE TABLE table2 (
  col2_0 BIT(24),
  col2_1 INT2,
  col2_2 TIMETZ NOT NULL,
  col2_3 TIMESTAMPTZ,
  col2_4 BIT(2),
  col2_5 FLOAT8,
  col2_6 STRING AS (lower(NULL)) VIRTUAL,
  col2_7 INT8,
  PRIMARY KEY (col2_1),
  INDEX (col2_2, col2_4 ASC) STORING(col2_0),
  UNIQUE (col2_2)
);

INSERT
  INTO table2 (col2_0, col2_1, col2_2, col2_3, col2_4, col2_5)
VALUES (NULL, 14831, '20:09:25.985305-12:13:00', '1997-06-25 14:53:21.000746+00:00', B'00', 0);

INSERT
  INTO table2 (col2_1, col2_2, col2_3, col2_4, col2_5)
VALUES (0, '20:30:19.373128-12:02:00', '1970-01-12 03:46:40+00:00', B'00', 0);
