[Buildroot] [PATCHv2 3/4] nano: enable ncursesw support

[Gustavo Zacarias <gustavo@zacarias.com.ar>]

Enable support for ncurses widechar by specifying the proper
ncursesw-config when it's enabled, otherwise keep the old trick in place
when it's not to avoid automatically picking up the host/distro one.
