URL: https://github.com/apache/doris/pull/65825
### What problem does this PR solve?
Issue Number: None
Problem Summary:
The Kerberos external regression suites can run concurrently against the
same Hive Metastore. Both `test_non_catalog_kerberos` and
`test_two_hive_kerberos` used the database name `test_krb_hive_db`.
Creating an external HMS database with `IF NOT EXISTS` performs a check
followed by a create operation. When both suites create the database
concurrently, both checks can observe that it is absent, and one request then
fails with an HMS `AlreadyExistsException`.
Use a dedicated `test_non_catalog_krb_hive_db` database for the non-catalog
Kerberos suite. This isolates its fixture from the two-Hive suite without
changing the tested export, outfile, HDFS, or Kerberos behavior.
### Release note
None
### Check List (For Author)
- Test: Static validation
- `git diff --check`
- Verified the two concurrent Kerberos suites no longer share the same
HMS database name
- Behavior changed: No
- Does this need documentation: No
