[SC-5406] Disable com.databricks.sql.acl.HiveCheckPermissionRuleSuite.Named UDFs

## What changes were proposed in this pull request?
HiveUDAF will not accept null function wrapper (after we have https://github.com/databricks/spark/pull/144). We will first disable `com.databricks.sql.acl.HiveCheckPermissionRuleSuite.Named UDFs` and then we can get apache#144 in.

## How was this patch tested?
n/a

Author: Yin Huai <yhuai@databricks.com>
