Remove the option of using the libcurses package directly, i.e. forcing
everyone to use the Haskell terminfo package.

The following patch updated the status of issue1366 to be resolved:

* Resolve issue1366: remove unreachable code for direct ncurses use. 
Ignore-this: d63652e5d82ac9e5029c53ba25d1deac
The C ncurses library is only used directly if the Haskell Terminfo
library is not available.  As Haskeline is now mandatory, and
Haskeline depends on Terminfo, direct libncurses use is unreachable.
