pipewiresink: copy metadata into pipewirepool buffers

Browse source 
If the pipewiresink needs to copy the GStreamer buffers to the PipeWire
buffers, because the upstream element didn't use the pipewirepool, the
metadata must be copied, too. Otherwise the pipewire datas will be
filled with the metadata from the buffer during the initialization and
not the currently used buffer.

For example, without copying the metadata the buffer timestamp will be
missing on the pipewire buffers.
