Issue 6619 - test_dblib_migration fails on RHEL10 (#6620)

* Issue 6619 - test_dblib_migration fails on RHEL10
Test test_dblib_migration fails on RHEL10 because bdb is not supported.
Test should be skipped in that case and libdb should provide a function to check if server can starts on bdb

Issue: #6619
