[SPARK-15839] Fix Maven doc-jar generation when JAVA_7_HOME is set
## What changes were proposed in this pull request?
It looks like the nightly Maven snapshots broke after we set `JAVA_7_HOME`
in the build:
https://amplab.cs.berkeley.edu/jenkins/view/Spark%20Packaging/job/spark-master-maven-snapshots/1573/.
It seems that passing `-javabootclasspath` to scalac using scala-maven-plugin
ends up preventing the Scala library classes from being added to scalac's
internal class path, causing compilation errors while building doc-jars.
There might be a principled fix to this inside of the scala-maven-plugin
itself, but for now this patch configures the build to omit the
`-javabootclasspath` option during Maven doc-jar generation.
## How was this patch tested?
Tested manually with `build/mvn clean install -DskipTests=true` when
`JAVA_7_HOME` was set. Also manually inspected the effective POM diff to verify
that the final POM changes were scoped correctly:

/cc @vanzin and @yhuai for review.
