package/zsh: add /bin/zsh to /etc/shells

Browse Source 
When zsh is selected, /bin/zsh is not added to /etc/shells
(see man shells). So, login tools like dropbear reject the ssh
connections for users using zsh as shell in /etc/passwd.

buildroot authpriv.warn dropbear[853]: User 'kubu' has invalid shell, rejected
