sdl: Disable warnings of old SDL2 version by the default

All the old SDL2 version warning messages are now disabled by default. To enable it, you can set the CGO_CPPFLAGS environment variable such as the following: CGO_CPPFLAGS=-DWARN_OUTDATED go build or CGO_CPPFLAGS=-DWARN_OUTDATED go get -v github.com/veandco/go-sdl2/sdl Signed-off-by: Lilis Iskandar <[email protected]>
