[lldb] Add terminfo dependency for ncurses support

For some operating systems (e.g. chromiumos), terminfo is a separate
package and library from ncurses. Both are still requirements for curses
support in lldb, individually.

This is a rebase of this original spack commit:
spack/spack@9ea2612

Without this fix, LLDB cannot be built on these systems.

Fixes #101368
