MDEV-15789 - mysqlslap use incorrect table def

The bug arises when one uses --auto-generate-sql-guid-primary (and
--auto-generate-sql-secondary-indexes) with mysqlslap and also have
sql_mode=STRICT_TRANS_TABLE.

When using this option, mysqlslap should create a column with varchar(36),
but it appears to create it as a varchar(32) only. Then if one has
sql_mode=STRICT_TRANS_TABLES, it throws an error, like:

  mysqlslap: Cannot run query INSERT INTO t1 VALUES (...)
  ERROR : Data too long for column 'id' at row 1

Upstream bug report: BUG#80329.
