Generates `package_symbol_tools.py` in the out directory, which:
- builds `upload_system_symbols` (written in Go, so unable to be built
directly through Chromium's BUILD files)
- packages it, along with the remaining tools and scripts necessary to upload
system symbols on a macOS system.
Packages everything necessary to extract and upload system symbols on a macOS
system into `symbol_tools.zip` in the out directory.
