[bug#49235] [PATCH] gnu: Add oneko.

[Timotej Lazar <timotej.lazar@araneo.si>]

* gnu/packages/toys.scm (oneko): New variable.
---
This adds the oneko version of the original xneko toy. The license
statement seems to be at the end of README (not sure as I can’t read
Japanese), but Debian and FSF agree it’s in the public domain.

`guix lint` complains about a newer version, but the only differences
are a somewhat less broken build system and an additional bitmap of the
BSD daemon, which is trademarked. I opted for this version instead of
basically reverting all changes from the newer one.

Thanks!
Timotej
