Fix the regression introduced in #<!-- -->149148 that incorrectly explicitly linked `clangTransformer` when dylib was used.  As a result, the executables linking to `clangTidyLLVMModule` would end up linking both the dylib and a number of static clang libraries, leading to complete mayhem and undecipherable segmentation faults.
