[PATCH proxmox-backup] fix #7024: pxar: show archive summary for legacy and data mode

[Shan Shaji <s.shaji@proxmox.com>]

earlier, the archiver summary was only being shown when the change
detection mode is metadata. To improve this, log the total number of
files and the amount of data re-encoded for legacy and data modes
as well.

 **note**: will send follow up patches for the verbose option and logs
 improvement.
