IMPALA-14546: Fix jdbc driver urls in test_postgres_jdbc_tables
TestPostgresJdbcTables.test_postgres_jdbc_tables uses hardcoded paths
for JDBC driver URLs:
"/test-warehouse/data-sources/jdbc-drivers/postgresql-jdbc.jar".
This doesn't work correctly when running on Ozone where we need the
prefix of "ofs://localhost:9862/impala".
This patch fixes the issue by constructing the driver URL with
FILESYSTEM_PREFIX which is "ofs://localhost:9862/impala" on Ozone.
See more in bin/impala-config.sh about how it's set for different
filesystems.
Tests:
- Ran the test on Ozone.

> custom_cluster/test_ext_data_sources.py's
> TestPostgresJdbcTables.test_postgres_jdbc_tables is consistently failing as
> it is unable to get the postgres JDBC driver:
> {noformat}
> E InternalException: Data source DataSource{name=impalajdbcdatasource,
> location=, className=org.apache.impala.extdatasource.jdbc.JdbcDataSource,
> apiVersion=V1} returned an error from prepare(): Failed to retrieve total
> number of records: Failed to copy JDBC driver from
> '/test-warehouse/data-sources/jdbc-drivers/postgresql-jdbc.jar' to local
> filesystem.{noformat}
> For tests to work properly on Ozone, they need to use
> WAREHOUSE_LOCATION_PREFIX or FILESYSTEM_PREFIX when referring to filesystem
> locations. The code that loads the Postgres JDBC driver into Ozone uses the
> prefix, but this test doesn't. The test needs to be updated to use the prefix.
