Effect AIDL: remove the shared_lib dependency for example binary

They will be dlopen so no need to add the shared_lib dependency.
But we need to add them as PRODUCT_PACKAGES in base_vendor.mk

Bug: 258124419
Test: build and boot cuttlefish, change effect lib path in Android.bp
and audio_effects_config.xml and bootup.
