Remove libvintf from libandroid_runtime

We'd like to limit the usage of libvintf because of its
performance/memory impact. By removing VintfObject and VintfRuntimeInfo
classes from preloaded-classes list, we can avoid loading libvintf from
libandroid_runtime. A new JNI library (libvintf_jni) is loaded only when
it's actually used.
