transaction: extract backupentry registration in a dedicated function

We are about to use the 'backupentry' mechanism to allow cleaning up
transaction-related temporary files (such as 'changelog.i.a'). We start
by extracting the entry registration into its own method for easy reuse.

At that point, I would like to rename the backup-file related variable to
something generic but I'm a bit short of ideas.
