mov: Do not blindly disable advanced edit lists if use_mfra_for is set 

This was a bug/mistake in dae3679a9b.

use_mfra_for by defintion only has an effect on fragmented MP4 files,
making the check not only redundant, but also broken if a user used
the option globally (i.e. set on non-fragmented MP4s).
