bufferlist: Ensure buffer and buffer list writability matches

Thanks for looking into this, but this is unfortunately API/ABI breakage. It
was also one of the things that I thought of, however:

a) existing binaries will only call gst_mini_object_ref() due to it being an
inline function before
b) it's perfectly valid to call gst_mini_object_ref/unref() on buffer lists,
and code does that. There are code paths that handle buffers and buffer lists
the same way as a generic mini object
