Resolve copyright/licensing issues

MKube is licensed under EUPL1.2-only, but mkube cannot be distributed as a binary currently without violating copyright/licenses of some dependencies.

Most of Mkube's dependencies are licensed under MIT or Apache 2.0 licenses and those are perfectly fine.
Nonetheless, two libraries one library that Mkube uses do does not allow redistribution under derivative works:

• pavao (dependence of remotefs-smb) is licensed only under GPL3+, this would cause the MKube binary to be licensed under GPL3 (due to EUPL1.2-only compatibility with GPL3) which is not terrible. Mkube binary without smb support can still be licensed under EUPL1.2-only.
• tmdb-api (direct dependency) is a more severe question as it is not licensed under any license at all. Therefore no mkube binary can be redistributed. tmdb-api is actually licensed under the MIT license, so no problem.
