Fix license declarations in package

[PhilippWendler]

The Ivy and Maven metadata claim that this package is under the MIT license, but actually it is under LGPL-3.0-or-later AND MIT, correct?

Furthermore, the Ivy metadata claims that libedit and libtinfo are under the LLVM Release License, but this is also not correct. According to the copyright info of the Debian package, libedit is under BSD-3-Clause, but the situation for libtinfo is more complex (if I read it correctly, it is BSD-3-Clause AND MIT AND X11 with a long list of copyright holders that need to be mentioned).
Maybe this is a reason to redecide #10 and stop bundling them?
