tools: remove obsolete entries from license

The LICENSE file has a few entries for things that no longer ship with
the code base. They are installed via npm instead. Remove them from the
license file.

Running the license builder on a fresh checkout will
result in errors until this change lands, since the necessary
information is not in the source tree until the `npm install` happens.
