`mvn site` by JDK 7 fails due to error related to spotbugs which does not
support Java 7.

```
Since we are using JDK 7 in the Dockerfile, dev-support/bin/create-release
is affected too.
The cause is obsolete <reporting> entries of pom.xml for already resolved
[MSITE-443](https://issues.apache.org/jira/browse/MSITE-443).
We can safely remove the <reporting> entry. `mvn site` generates same
contents without the entry. spotbugsXml.xml are generated regardless of it (on
`mvn compile spotbugs:spotbugs` using JDK 8).
