Make audio_remote_submix build with the VNDK.

When the vndk is enabled (BOARD_VNDK_VERSION=current),
vendor libraries must only link against vendor variants
in the build system. This means that they receive restricted
sets of headers and that automatic global headers are restricted.

Test: build audio_remote_submix with BOARD_VNDK_VERSION=current
