Fix gerrit-extension-api-X.Y-all-sources.jar

The Maven artifact gerrit-extension-api-X.Y-all-sources.jar that
should contain the sources of the gerrit-extension-api doesn't contain
any source from the com.google.gerrit.extensions package. Configuring
the Maven plugin 'maven-source-plugin' fixes this.
