DRILL-7130: Add test for the issue (#567)

- The issue reported in DRILL-7130 can be easily reproduced by having a table with 100 rows and 1 column (of 100 bytes). Add a single row of size < than 100 bytes.
- Query the parquet file.

+DRILL-7130/VarLenNullableFixedEntry.parquet is the table queried from DRILL-7130.sql.
+
+The table contains 100 rows with 1 column (size 100 bytes) and 1 row with column of size 50 bytes.
+Querying such a table should reproduce the issue reported in DRILL-7130.
