roll: pigweed, pw_toolchain: pw_transfer: Add a delay after opening a stream to delay transfer start

If a start chunk is sent too quickly after a stream is opened, it
gets dropped because the server hasn't set the on_next_callback.
Add a short (10ms) delay to give some time for the stream to open.
