Move this to BaseJNIOnLoadDelegate::Init()

[Torne, 2015/02/13 14:08:04]

Hm. The JNI environment isn't passed to the init functions, which makes this
mildly annoying. Do none of them need it, or are they just all getting it with
AttachCurrentThread? If several of the init functions need it, then maybe it
should get passed to Init() as well as to RegisterJNI()..
