No longer need to switch to Unified mode for binary file

On SideBySide diff UI, click the InlineHyperlink to navigate
previous/next patch, Gerrit will switch to Unified mode if the next
patch is binary file and will never switch back to SideBySide mode
even if it would run into non-binary file later.

As 6963c5f is available in stable-2.6, Gerrit need not to switch
from SideBySide mode to Unified mode for binary file anymore.
