various README nits (#470)

don't capitalize "berg" in "Codeberg" spelling. Codeberg's official
sites does not seem to do so.

switch from "GPLv2" to "GPL-2.0-or-later" according to the spdx short
identifier: https://spdx.org/licenses/GPL-2.0-or-later.html

explicitly mention that Imlib2 needs to be built with X11 support.
