wayland/buffer: Create EGLImage with no context

Browse Source 
Since a wl_buffer is independent of the GL context in use (unlike, e.g.,
a GL renderbuffer), EGLImages with the EGL_WAYLAND_BUFFER_WL target must
pass EGL_NO_CONTEXT as the context. Quoting from the
EGL_WL_bind_wayland_display spec:

    After querying the wl_buffer layout, create EGLImages for the
    planes by calling eglCreateImageKHR with wl_buffer as
    EGLClientBuffer, EGL_WAYLAND_BUFFER_WL as the target, NULL
    context.

The check was already present inside _cogl_egl_create_image.
