wayland/buffer: Try realizing EGLStream before EGLImage buffer
Currently, it is assumed that if querying the EGL_TEXTURE_FORMAT of a Wayland buffer succeeds it is an EGLImage. However, this assumption will no longer hold on upcoming versions of the NVIDIA EGL Wayland driver which will include support for querying this attribute for EGLStream buffers as well. Hence, we need to check if buffers are EGLStreams first. Fixes #488 https://gitlab.gnome.org/GNOME/mutter/merge_requests/477
