Fix Groovy dependencies

Starting with version `2.5.0` the `groovy-all` is a BOM.
That is not clear how it works as a regular dependency in our Gradle
config, but generated pom is wrong with this dependency.
(Gradle bug?)

* Specify explicit required dependencies for `spring-integration-groovy`
and `spring-integration-scripting` modules
