[yocto] poky-contrib maintenance

[Flanagan, Elizabeth]

Folks,

poky-contrib clones are getting quite bulky again. I'm seeing branches
that haven't been touched in two years. I'm going to ask folks to
please go in and remove unneeded branches. In a week, I'll be
contacting folks with really old branches to verify if they're still
needed.

So, please, be kind and clean up contrib space. Thanks!
