[Buildroot] [git commit] package/zsh: add /bin/zsh to /etc/shells

commit: https://git.buildroot.net/buildroot/commit/?id=8dbfd500006c630a0299e384965045056fdb4d3b
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

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
