baseparse: put buffer in a correct state after gst_adapter_get_buffer call

Browse source 
We must make the buffer writable to write its PTS and DTS, and also
reset its duration.

The behaviour is now the same as before commit c3bcbadd, except metas
might still be attached to the buffer extracted from the adapter.
