Subject: [PATCH] Add an option to skip updating submodules if only building
 for java

Summary:
When invoking `./build-infer.sh java`, there is no need to update the facebook-clang-plugins submodule that is done as part of the `autogen.sh` script. The submodule update takes a very long time and can be skipped when building only for java
Closes https://github.com/facebook/infer/pull/557
