[Noetic] spinnaker_camera_driver fails to build on armhf

[sloretz]

Hey @tonybaltovski,

It looks like spinnaker_camera_driver isn't building on some platforms:

• Ubuntu Focal armhf

I'm planning to add all chronically failing packages to per-platform blacklists later this week. That just means the buildfarm won't try to build them every day.

When all issues causing the build failures are resolved, please make a PR to the production branch on ros_buildfarm_config removing it from the package_blacklist:

• release-armhf-build.yaml

@sloretz there is no SDK for armhf. It can be blacklisted permanently.
