Revert 275652 "Remove unneeded JNI registrations."

This has broken the Android WebView build by introducing an absolute
path into the generated makefiles, rendering them nonportable.

> Remove unneeded JNI registrations.
> 
> Rather than registering all jni bindings at startup, only get references
> to the class object for those files which require bindings. All others
> are satisfied by exporting symbols which can be found automatically by
> dalvik.
