Licence attribution of new meson python scripts

[Hugh McMaster]

Hi all,

I'm updating Debian's copyright file for FreeType 2.10.4.

Whose name should be attributed for copyright of the python scripts in
builds/meson?

The files have no copyright notation, but were created by David. In
saying that, most other files are copyright David Turner, Robert
Wilhelm and Werner Lemberg, so just wondering how to attribute here.

Thanks,

Hugh
