Ensure copyright owner is correct in all repos

Should be based on https://github.com/libero/community/blob/master/LICENSE

We have amended the copyright owner to be Copyright (c) 2019 Libero in some instances.

I may not have caught all the projects as I haven't pulled all the libero ones down:

$  libero find . -maxdepth 2 -name 'LICENSE' -exec grep -Hn "Copyright" {} \;
./reviewer/LICENSE:3:Copyright (c) 2019 Peter

I have PR's for the 5 incorrect ones. If you can think of any other projects that I should look at then let me know.
