mxfdemux: Handle EOS with non-frame wrapping

Browse source 
When reaching the end of non-frame wrapping track in pull mode, we want to force
the switch to the next non-eos pad. This is similar to when we exceed the
maximum drift.

Fixes issues on EOS where not everything would be drained out and stray errors
would pop out.
