cnetaddr_tostring_canonical_ipv6 test fails during `make check` on fresh clone of repo on macOS 10.14 #21967

Expected behavior make check completes successfully when run on a freshly cloned Bitcoin Core repo.

Actual behavior make check fails with the following errors --

test/net_tests.cpp:446: error: in "net_tests/cnetaddr_tostring_canonical_ipv6": check net_addr.ToString() == expected_canonical_representation_output has failed [2001:db8::1:1:1:1:1 != 2001:db8:0:1:1:1:1:1]

To reproduce

1. Follow the build steps available here -- build-osx.md -- on a macOS 10.14. Install all required dependencies and the first set of optional dependencies. Use Wallet (only SQlite) and GUI Support configuration.
2. Proceed until the "2. Compile" step under the "Building Bitcoin Core" section, at which point running make check will result in the error above.

System information

Not running Core yet; this is a build time issue when running make check on the bitcoin repo cloned from https://github.com/bitcoin/bitcoin/ master branch at commit c8571486364d6e9ca8c86bd1c81e230ca64f8904.
