teeworlds: fix meta.license

Replace stringy license with a list of all used licenses.

The original meta.license said that the license was BSD-style but this information has been outdated for a long time.
The license was changed in 2008: https://github.com/teeworlds/teeworlds/commit/bc108df382b5ac4ca637bf97ba9b2d8b2d83e58f#diff-7bb54d15ef4c4e0f20bb24add68a12fccced9925b304eaa696023143d278ea26.
The current license is clearly the zlib license and below that some notes about the licenses of `datasrc` (and `data`, which has not existed in the tree for many years), the fonts in `datasrc` and the libraries in `src/engine/external`.
See https://github.com/teeworlds/teeworlds/blob/master/license.txt for the current version of the license.
The meta.license string has been unchanged since the commit adding teeworlds in 2009: e71dbdbb8334152dbf3083801d194b2f88cee9b4.

See issue #269788.
