fixes flutter#191171

This is the linux equivalent of the windows change:
flutter#190256

On desktop we normally need to have an explicit resolution step for MSAA
to work, this adds that explicit step. On linux we were already blitting
from this framebuffer so we didn't need to provide an explicit resolve
step, it already existed.

I also removed code about using bgra. This was impeding our usage of
MSAA render buffers, on linux I don't think there is a reason we have to
use BGRA.
