Create a checker-inference-qual.jar file

[wmdietl]

At the moment all CF classes are added to the runtime classpath:
https://github.com/typetools/checker-framework-inference/pull/72/files#diff-d80679221256a0135d284f4188189a2aR131

Like with checker-qual.jar, we should create a checker-inference-qual.jar that only contains the dependencies that are needed on the compilation classpath.
