archive should preserve the extended attributes

[omar-polo]

maybe we should have something to preserve these xattrs on archives. GNU tar has (obviously) an option for this.

this actually still has to be discussed, noting it here to avoid forgetting it.

Modification time should be preserved; not sure if that is under xattrs, but as of plakar v0.4.22-alpha, modtime is not restored:

$ ls -al znew # mod time on the restored file is the write time
-rwxr-xr-x 1 jaten jaten 5071 Feb 17 20:09 znew
$ ls -al /bin/znew # which does not match the mod time on the original backedup file.
-rwxr-xr-x 1 root root 5071 Apr  8  2022 /bin/znew
