  Log Message:
  -----------
  [clang] use relative paths for builtin headers during module compilation (#68023)

When including builtin headers as part of a system module, ensure we use
relative paths to those headers. Otherwise the module will fail to compile 
when specifying relative resource directories without extra search paths.
