[Buildroot] [PATCH 5/7] package/tmux: add /usr/bin/tmux to /etc/shells

[Yann E. MORIN <yann.morin.1998@free.fr>]

Romain, All,

On 2018-01-14 22:03 +0100, Romain Naour spake thusly:
> When tmux is selected, /usr/bin/tmux is not added to /etc/shells
> (see man shells). So, login tools like dropbear reject the ssh
> connexions for users using tmux as shell in /etc/passwd.
> 
> buildroot authpriv.warn dropbear[853]: User 'kubu' has invalid shell, rejected

No need for an append-assign (+=) here, just use a plain asignment (=).
