nest: fix python3 brew dependencies
nest: fix python3 brew dependencies

The homebrew dependencies `numpy`, `scipy` and `matplotlib` need the `with-python3` flag for python3 installation.

Apparently, `nest` changed directory name in the tar, all other files are the same - but still the sha changed.

Bumped revision.

Closes #5293.
