commit 04ecdb08d45795646becb3535c477c006f5f7c6b
Author: Noriko Hosoi <nhosoi@redhat.com>

Ticket #47804 - db2bak.pl error with changelogdb
Bug description: Backup utility db2bak[.pl] copies not just backend
db files but also changelog db files, which is not associated with
the backend instance, but the backend code blindly expected it.
Fix description: If the copying directory is a changelog db dir,
skip retrieving the backend instance info and just copy the files
underneath
