It looks like the lldb test suite depends on these files being copied as well, so I've updated it to depend on the runtimes-test-depends target to ensure the libc++ headers have been installed to the fake prefix in the build dir first. Hardcoding these paths is unfortunate but I couldn't see an obviously better solution. This dates back to https://reviews.llvm.org/D133973
