Update gol script

[k127]

Fix issue for symlinked gol script on macos/unix:

$ ./gol

Thanks for submitting this! (Sorry it took so long to review, have been busy on the Python side). I tried to reproduce the error -- on my configuration, the JAR loads properly even if referenced via symlink.

gol/0.1.9
OpenJDK 19
Ubuntu 22.04

I used this command to create symlink:

ln -s /path/to/gol gol

It also works if the target is on another volume.

On which OS are you experiencing this issue?

On the other hand, your proposed code works fine, so I may just go ahead and merge it. I just wanted to make sure there isn't a secondary issue that interferes with the symlink resolution.
