Sebastian Dröge 1469453cb9 ffmpegcolorspace: Fix IYU1 support 
Fix conversions to IYU1, they allocated infinite amounts of memory before
because no conversion to IYU1 was actually implemented and it was running
into an infinite loop trying to find suitable intermediate formats.

Also fix the stride and sizes used for IYU1.
