  Log Message:
  -----------
  clang-tidy: Make tests more hermetic

Make check_clang_tidy.py not just pass -format-style=none by default
but a full -config={}. Without this, with a build dir outside of
the llvm root dir and a .clang-tidy config further up that contains

  CheckOptions:
    - key:          modernize-use-default-member-init.UseAssignment
      value:        1

these tests would fail:

   Clang Tools :: clang-tidy/checkers/cppcoreguidelines-prefer-member-initializer-modernize-use-default-member-init.cpp
   Clang Tools :: clang-tidy/checkers/modernize-use-default-member-init-bitfield.cpp
   Clang Tools :: clang-tidy/checkers/modernize-use-default-member-init.cpp

After this change, they pass fine, despite the unrelated
.clang-tidy file further up.
