hydra: bayfront: Use 'guix publish --cache'.

Browse source 
* hydra/bayfront.scm (services): Use the 'cache' and 'ttl' options of
'guix-publish-service-type'.
* hydra/nginx/bayfront.conf,
hydra/nginx/bayfront-locations.conf: Cache narinfos and nars for a
shorter period; allocate less space for these caches.
