Patchwork [2/3] ncurses: move only libncurses and libtinfo to base_libdir

The previous approach to moving the ncurses libraries to
base_libdir was too aggressive, and it broke curses support
in python.

Instead, move only libncurses, libncursesw, and libtinfo to
base_libdir and leave the remaining libraries in libdir.

Also delete ${libdir}/terminfo as it never gets packaged to
avoid a QA warning.

This fixes [YOCTO #2070] and is a partial fix for [YOCTO #1937].

Hello Scott,

package splitting doesn't seem to work anymore. Libs that previously had
their own package now end up being stored in the main ncurses package.

Regards,
Andreas

Thanks for reporting this, Andreas. I am working on a fix for it now. My 
apologies for the trouble.
