camel-jibx doesn't build when used with -Dmaven.test.skip=true

The camel-jibx component uses maven-antrun-plugin to call the JiBX binding compile task.

Even if this plugin is called during process-test-classes (as it uses target/test-classes, if we try to build using:

mvn clean install -Dmaven.test.skip=true

it fails:

[INFO] — maven-antrun-plugin:1.5:run (default) @ camel-jibx —

main:

The maven-antrun-plugin is called whereas it shouldn't.
