pgsql: Fix lookup error in extended stats ownership check

Fix lookup error in extended stats ownership check

When an ownership check on extended statistics object failed, the code
was calling aclcheck_error_type to report the failure, which is clearly
wrong, resulting in cache lookup errors. Fix by calling aclcheck_error.

This issue exists since the introduction of extended statistics, so
backpatch all the way back to PostgreSQL 10. It went unnoticed because
there were no tests triggering the error, so add one.

Backpatch-through: 10, where extended stats were introduced
