[lldb] fix building with panel.h being in /usr/include/ncurses/

[llunak]

Summary

My openSUSE 15.2 has /usr/include/curses.h as a symlink to /usr/include/ncurses/curses.h , but there's no such symlink for panel.h . Prefer using /usr/include/ncurses for the includes if they are found there by the CMake check.

I am not a cmake expert. Might be a good idea to check the git log for people with more cmake expertise?

[mgorny]

I suppose this makes sense. Testing it on some more systems might be good but I guess buildbot will take care of that.
