Handle SHOW VARIABLES returning no row

MySQL 5.7 has introduced permission limiting for the "SHOW VARIABLES"
command; the MySQL dialect will now handle when SHOW returns no
row, in particular for the initial fetch of SQL_MODE, and will
emit a warning that user permissions should be modified to allow the
row to be present.
