lavfi/ebur128: fix format negociation for output.

Before this change, the audio input and output formats are set
independently, so the lavfi negociation could pick different settings
for the input and output. This is particularly true for the channel
layout settings, where multiple choices were available.

Fixes Ticket2342.
