Revert "Drop tools/gyp from dependencies."

This reverts commit 724a97d08d35b69d934b1c09fc2e0f4dd4d47f76.

Reason for revert: We have this error during gclient runhooks on some
windows bots:
Downloading https://commondatastorage.googleapis.com/chromium-browser-clang/Win/clang-334100-1.tgz .......... Done.
Traceback (most recent call last):

    dia_path = os.path.join(GetVSVersion().Path(), 'DIA SDK', 'bin', 'amd64')
  File "src/tools/clang/scripts/update.py", line 388, in GetVSVersion
    import gyp.MSVSVersion
ImportError: No module named gyp.MSVSVersion

Looks like if toolchain is not downloaded before then it failed to
download it from scratch.
