lens: Change lens' listed license from MIT to their own proprietary l…

…icense.

Although Lens is based on a free core component ("OpenLens"), the tarballs
provided by Mirantis include a proprietary version of Lens that requires
a subscription.

As the proprietary option offers additional features, it would not be wise
to simply rewrite the derivation and base it on the FOSS source code.
Instead, implementing a new derivation for OpenLens is likely the better
approach.
