With more GPUs it might happen that server used different render node from the one we pick from the list. This would cause DMA-BUF to fail to import so we use Wayland client library to obtain wl_display in order to initialize EGLDisplay using same render node and have previous approach as a fallback. Also everyone else uses EGL_LINUX_DMA_BUF_EXT target for importing EGLImages from DMA-BUF file descriptors so use it as well to be sure we import buffers same way as they are produced.
