[Buildroot] [git commit branch/2019.08.x] package/connman: clarify license of client code

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=5bb64c811d51019678a088c96630c3d56b35036a
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2019.08.x

While the core connman code is licensed under GPL-2.0, the client code is
GPL-2.0+ for compatibility with readline (which is GPL-3.0+).

Extend the _LICENSE with this info to clarify that linking against
readline is OK licensing wise.
