[RFC v3 3/9] Many pages: [GPL-2.0-or-later] Use SPDX markings

[Alejandro Colomar <alx.manpages@gmail.com>]

To simplify understanding which license applies to each file,
let's use SPDX markings, which are simple, informative, and
commonly used in many projects.
Let's also follow REUSE <https://reuse.software/> conventions.
