Can this also be removed from our android_deps?

Where are you looking? The only place I see it, if I

$ git grep giflib.gyp

is in gyp/images.gyp. And that is still needed for SkGIFMovie.cpp. I know
there's been a lot of hate for SkMovie, but I think the simplest way to stop
requiring giflib is to switch that file to use SkCodec.

You're right, my mistake.
