ncurses: move runtime utilities to $out

All the programs provided by ncurses were being installed to the $dev
output, but several of them are intended for runtime use, e.g. to
operate on the running terminal. These user-facing programs are moved to
the $bin output.

Several packages referred to "${ncurses}/bin" or "${ncurses.dev}/bin" at
runtime; these paths are also updated to refer to "${ncurses.bin}/bin".
