moveconfig.py: Fix more Python3 UTF issues

With the move to using Python 3 for real, we encounter two different
issues.  First, the file include/video_font_data.h includes at least one
UTF-16 character.  Given that it does not include any CONFIG symbols it
is easiest to just ignore this file.  Next, we encounter similar
problems with some dts/dtsi files that come from Linux.  In this case
it's easiest to simply ignore all dts/dtsi files as there will not be
CONFIG symbols for us to migrate in them.
