[bug#54351] [PATCH] gnu: Add emacs-xah-fly-keys.

[Jai Vetrivelan]

The license of xah-fly-keys has been updated to gpl3 with commit
6e974bd21f2d42aaa6d0b331a162cb554085b72e. I think the patch can now be
applied with commit pointing to current HEAD.

I terribly bad at footnotes, that link was meant for

“One package in emacs-xyz.scm is /gpl2-only/, which upstream has
updated to /gpl3+/. [1]”
