    substitute: Download nar from another server upon ETIMEDOUT.
    
    Previously, 'guix substitute' would fail abruptly with something like:
    
      guix substitute: warning: while fetching 
https://ci.guix.gnu.org/nar/lzip/…-example: server is somewhat slow
      guix substitute: warning: try `--no-substitutes' if the problem persists
      guix substitute: error: connect*: Connection timed out
      substitution of /gnu/store/…-example failed
    
    * guix/scripts/substitute.scm (network-error?): Add ETIMEDOUT.
