Split the clangTidyRE rule

* Add clangTidyDepRE, which is an order-only dependent of
  the new simplified clangTidyRE rule.
* Remove escapeSingleQuotes, used only by the old bash command.
* Remove extra space when TIDY_TIMEOUT is not defined.
* In clang-tidy calls,
  use moduleFlags to match the clang/clang++ commands.
