renderer/native: Also wrap flip closures for EGLStreams

Browse Source 
When using the EGLStream backend, the MetaRendererNative passed a
GClosure to KMS when using EGLStreams, but KMS flip callback event
handler in meta-gpu-kms.c expected a closure wrapped in a closure
container, meaning it'd instead crash when using EGLStreams. Make the
flip handler get what it expects also when using EGLStreams by wrapping
the flip closure in the container before handing it over to EGL.
