 libedit: fix misbehaviour with callback-based API

 rl_callback_read_char does el_set(e, EL_UNBUFFERED, 1) after running the
 client-supplied callback. However, if the callback ran
 rl_callback_handler_remove, this undoes part of what that function did.
 So,
 don't do it if the callback has been removed.

 This fixes python's issues with not restoring terminal state on exit and
 incorrect prompt display, and should avoid reintroducing the problem
 described
 in <http://gnats.netbsd.org/48957>.
