[Scarthgap] Build error for cartographer

[mark-bchoi]

Hi,

As reply https://github.com/ros/meta-ros/discussions/1221#discussioncomment-11215846 , I file it as a bug.

I found this issue in building cartographer and it would be caused by legacy version of python3-shinix inherited by ROS.

As mentioned in https://github.com/ros/meta-ros/discussions/1221#discussion-7233112 , meta-ros have used older version and as python version upgraded, it would not cover latest python version.

error message is following.

For mitigation, I added BBMASK to remove legacy version to my distro file in advance, because I don't like touch meta-ros directly.

BBMASK += " meta-ros/meta-ros-common/recipes-devtools/python/python3-sphinx_1.6.7.bb "

Thanks for reporting this, @mark-bchoi . I'll try to take a look at this.
