[Build] Fix the manifest target and source information for jdbc projects (elastic#121888) (elastic#122239)

The nebula info broker plugin takes the information for the manifest from the java project settings rather then from
the compile task configuration. Instead of setting the compiler task configuration explicitly we now set the project
configuration accordingly. Also tweaked the javaTestCompile tasks to keep compiling with general minimum runtime version as we did before

(cherry picked from commit 6e6e42f)
