video: change --deinterlace behavior

This removes all GPL only code from it, and that's the whole purpose.
Also happens to be much simpler.

The "deinterlace" option still sort of exists, but only as runtime
changeable option. The main change in behavior is that the property will
not report back the actual deint state. Or in other words, if inserting
or initializing the filter fails, the deinterlace property will still
return "yes". This is in line with most recent behavior changes to
properties and options.
