This patch removes all non-Maven-central repositories from Spark's build, thereby avoiding any risk of future build-breaks due to us accidentally depending on an artifact which is not present in an immutable public Maven repository.

I tested this by running

```
build/mvn \
        -Phive \
        -Phive-thriftserver \
        -Pkinesis-asl \
        -Pspark-ganglia-lgpl \
        -Pyarn \
        dependency:go-offline
```

inside of a fresh Ubuntu Docker container with no Ivy or Maven caches (I did a similar test for SBT).
