ncurses: Update to version 6.5

ncurses: Update to version 6.5

- Update from version 6.4 to 6.5
- Update of rootfile
- --with-pkg-config-libdir as the previous default has been changed to $(LIBDIR) and this
   does not work and resulted in procps not building as it could not find ncurses.
- Likely other packages after procps would have also failed.
- Explicitly specifying the pkgconfig directory location worked.
