journal: Copy holes when archiving BTRFS journal files

Previously, the holes we punched earlier would get removed when
copying the file. Let's enable the new COPY_HOLES flag to make
sure this doesn't happen.

In my test, this drops a 800MB btrfs journal (without compression)
to 720 MB.

Fixes #22087
