preserve ownership for blockreplace backup files

shutil.copy2 does not attempt to preserve file ownership, which means
that backup files on local disk will normally be owned by root. This is
dangerous because it may cause unprivileged utilities such as rsync or
pg_basebackup to fail when operating on directories where the backup
files were created.
