hakuneko: 1.4.2 -> 5.0.8
hakuneko: 1.4.2 -> 5.0.8

HakuNeko switched to electron. Since this is the latest release the
broken status can be dropped. The original maintainer (Ruben Astudillo)
dropped support for the package so I decided to pick it up.

I based this on the simplenote package, and implemented the setuid fix
from the slack package.

Closes #45332
