gnu-maintenance: 'gnu' updater prefers tarball with same compression.

Fixes <https://issues.guix.gnu.org/59168>.

Previously 'guix build make --with-latest=make' would pick ".tar.lz",
rather than "tar.gz", because "tar.lz" happened to come first in the
<upstream-source> 'urls' field.

[better-tarball?]: New variables.
Sort TARBALLS according to BETTER-TARBALL?.
