[ruby/reline] Drop loading terminfo, remove fiddle dependency in

non-windows environment.
(https://github.com/ruby/reline/pull/769)

Reline works perfectly in most major terminal emulators without terminfo.
In minor/old terminal emulator, we used to get key bindings from terminfo, but I think it is not used so much.
