 PR/50496: Alex Kozlov: teach unzip to extract symlinks

 Our libarchive does not handle symliks yet, but later versions do.
 Set mode and times for symlinks. Finally handle hardlinks for
 completion although they are not handled yet by librarchive.

 AFAIK, even info-zip/unzip doesn't handle hardlinks.
 There is some vague mentioning in 'UNIX Extra Field' section of
 pkware's appnote.txt though.

 Thanks, I know; I was using at the file creation handling of the tar example
 client and I thought, why not? When/if they do it will just work.
