media/gpu/v4l2_vda: Use correct format for checking in import buffer.

The "output_format_fourcc_" may not be the final output format if an
image processor is needed to convert the format. (It is always
needed, the import mode is only supported with image processor)

Use "egl_image_format_fourcc_" instead, it will be the final output
format in both import/allocate mode.

Bug: b/72286007
Test: Play videos in ARC++.
