package/tmux: add /usr/bin/tmux to /etc/shells

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

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