Huaisi Xu 816735a032 IMPALA-3092: Set default value to NULL in AvroSchemaConverter ...

This change ensures that Avro tables created without column definitions
remain queryable if columns are added via ALTER TABLE. The bug was that
when synthesizing an Avro schema from the column definitions we used to
not add default values.
