Fix invalid solr.xml creation in SolrOutputFormat.java
Sometime after Solr 4.9, the `MapReduceIndexerTool` got busted because
invalid `solr.xml` contents were being written to the solr home dir zip. My
guess is that a 5.0 change made the invalid file start to matter.
The error manifests as:
```java
Error: java.lang.IllegalStateException: Failed to initialize record writer

The last version that I've successfully used `MapReduceIndexerTool` was
4.9, and I verified that this patch resolves the issue for me (testing on 5.1).
I spent a couple hours trying to write a simple test case to exhibit the error,
but I haven't quite figured out how to deal with the
`java.security.AccessControlException: java.io.FilePermission ...` errors.
