Upgrade/Install: Remove bundled theme files from $_old_files.

Because themes are updated independently of Core updates, any deleted files from bundled themes should not be included in the `$_old_files` list.

Any file included in this list is deleted on update, which could cause problems for sites with a given theme active if the removed files were required in earlier versions of that theme and that theme is not updated at the same time.

Props desrosj, costdev, SergeyBiryukov.
Fixes #56936.
