When a server publishes several URLs with different compression methods,
'guix substitute' can now choose the best one among the compression
methods that it supports.

Fixes &lt;https://bugs.gnu.org/33733&gt;.

Fixes a bug whereby 'guix substitute' would accept narinfos whose
signature does not cover the StorePath/NarHash/References tuple.
