Fix env not passing options of sbcl for it when running the script.

[lucasew]

This is a fix of the following error on Arch Linux.

/usr/bin/env: “sbcl --script”: File or directory not found

Thanks for this! I don’t know a lot about env, so pulling up the man page and finding out what this does was actually very helpful.

Thanks for your contribution!
