Merge #24262: upstream: Update minisketch subtree

8fcb19f Squashed 'src/minisketch/' changes from 89629eb2c7..7eeb778fef (fanquake)

Pull request description:

  Marco mentioned issues running the native valgrind job (it sets `-Werror`) on arm64 hardware due to compile errors:
  ```bash
  minisketch/src/minisketch.cpp:66:20: error: unused function 'EnableClmul' [-Werror,-Wunused-function]
  ```

  Pull the subtree to fix this. The only change here is sipa/minisketch#58.
