With this commit, this first set of software are now updated and build
successfully on my Arch GNU/Linux OS. It goes until Tar, but currently
stops before writing its final target (so we can go step by step to the
next software).

Following the discussion in Task #15699 [1], all software that come into
Maneage will be archived in a unified format. To do this, the downloaded
tarball from each software's webpage (or the version we already had) was
put in an 'orig' directory, then the following two commands were run (for
example for xz version 5.2.5):

    $ name=xz-5.2.5
    $ tar xf orig/$name.tar.gz \
      && tar -c -Hustar --owner=root --group=root \
             -f $name.tar $name/ \
      && lzip $name.tar \
      && rm -r $name/

But besides the formatting, the top directory within the tarballs is now
always just the name of the tarball without the 'tar.lz'. While most
software already follow that convention, some (like Zip or Unzip)
didn't. So they have also been corrected.

As one exception, for now, Make has not been updated because it would have
the same file name as before and we don't want to break any dependencies
(by modifying it, and thus its checksum). I tried bootstrapping Make's
latest commit (so the version identifier can be different), but there was a
bug when building the latest version on my computer and it has been
reported to its developers [2].
