Improve the yt-dlp.sh script (#248)

* Quote the `$0` variable to correctly handle spaces
* Change the shebang line to `/bin/sh` to avoid unnecessarily depending on bash
* Use the `exec` command to avoid having the shell process linger unnecessarily
* Change the mode to make the script directly executable
