Update Archive-Tar to CPAN version 1.62

  [DELTA]

  Important changes since 1.54 include: compatibility with busybox
  implementations of tar which was added by Mark Swayne; a fix so
  that write() and create_archive() close only handles
  they opened by Darrell K.; and a bug was fixed regarding the exit code
  of extract_archive which was spotted by and upstreamed from RedHat by
  Martin Cermak.
