Avoid creating sp<> from a pointer

The recommended practice is to use sp<>::make,
sp<>::fromExisting, or making copies from other sp<>.
This is to avoid various edge cases with RefBase.

Set ANDROID_UTILS_REF_BASE_DISABLE_IMPLICIT_CONSTRUCTION for
libaudioeffect_jni to catch non-recommended usages
as compile time.
