[llvm] [bazel] Fix building lldb without libedit (PR #184535)

[Keith Smiley via llvm-commits]

https://github.com/keith created https://github.com/llvm/llvm-project/pull/184535

We were always trying to compile the libedit file even if it wasn't used
because we were missing this conditional from cmake:
