hardcoded binary path

[spiderbit]

Inside nixos when the webserver tries to serve files it does not find the "/bin/cat" binary it apperently uses for that.

(setq elnode-send-file-program (locate-file "cat" exec-path))
(setq elnode-send-file-program "cat")

that or that solves that problem dont know which is the better fix, but both would be better than having a absolute path.

came here to make a pr on that. Also a nixos user

imho, elnode-send-file-program "cat" is sufficient.
not having cat in /bin/ is pretty normal, not having coreutils things in the path is much weirder.
