Aleix Boné 785f7cfee8 Fix nginx /cache regex
`nix-serve` does not handle duplicates in the path:
```
hut$ curl http://127.0.0.1:5000/nix-cache-info
StoreDir: /nix/store
WantMassQuery: 1
Priority: 30
hut$ curl http://127.0.0.1:5000//nix-cache-info
File not found.
```

This meant that the cache was not accessible via:
`curl https://jungle.bsc.es/cache/nix-cache-info` but
`curl https://jungle.bsc.es/cachenix-cache-info` worked.
