[BUG] Switch shell script: `chsh` fails.

[luigimasdea]

Describe the bug

chsh fails because, in the case of bash -> zsh switch, it takes as argoument which zsh, which returns /usr/sbin/zsh.
The problem is that the zsh path in sbin is not in /etc/shells.

Steps to reproduce

1. Install ML4W with Dotfiles Installer.
2. Execute .config/ml4w/scripts/shell.sh
3. The script executes chsh -s $(which zsh).
4. which zsh returns /usr/sbin/zsh.
5. /usr/sbin/zsh is not listed in /etc/shells, so chsh fails.

Expected behavior

chsh should take always /usr/bin/zsh as an argoument.
