videorate: clear discont on duplicated buffers

When videorate duplicates a buffer with a DISCONT flag, it copies the discont on
the first pushed buffer but fails to clear it for subsequent buffers. This
causes theoraenc!oggmux and possibly other elements to consider this a discont
stream.

Fix videorate to produce discont as the first buffer and after a flushing seek.

Fixes #580271.
