For our implementation of caching work, `DW_LLVM_AT_include_path` is not needed (or sysroot) unless there is a relative include path. 

I don't think I want to have an opinion here since this is not in the path CAS based caching compilation is done. This is fine as long as it is a configurable build configuration and people decide to scrub the sys root knows the tradeoff.

Also I really hope we don't use the name of SDK directory  to do some meaningful decision in lldb. @adrian-prantl we need to change that!
