Fix binary baseline & line-end problem

By default all baslines are run through diff-remove-timestamp. On a BSD
sed implementation, this means that a newline is added to the end of the
file, if no newline was there originally. This behavior differs from GNU
sed, which does not add a newline.

In this commit we unify this behavior by always adding a newline, even
when using GNU sed. This commit also disables the canonifier for a bunch
of binary baselines, so we do not have to change them.
