Add ffi feature to rockbox-slim for C exports
Gate pcm_squeezelite C exports behind an optional "ffi" feature to
avoid duplicate-symbol linker errors for crates that depend on the
rlib but don't need the C API. Enable the feature in crates/cli so
the final staticlib still provides the symbols for the hosted sink.
