exynos4: Part of Netflix fix

codeworkx pulled the Samsung colorformat patch from Insignal's
exynos-jb branch, which is an invalid source for exynos4 patches.

It was checking for an OMX codec name that didn't exist.

This still doesn't stop Netflix JPlayer failing in 10.1, but
does fix Netflix failing if you disable JPlayer by convincing
it that it's on an older Android version.
