Two fixes:
1. Windows: replaced broken 'mingw-w64-x86_64-autoconf/automake/
autoconf2.13/libtool' individual packages with the meta package
'mingw-w64-x86_64-autotools' which is what actually exists in the
MINGW64 repo (the individual ones don't).
2. macOS: added 'zlib' to brew install (configure complained the
--with-zlib-dir was empty).
Also fixed the chaindb equivalence test step in build-all.yml to
run the correct binary: 'build/bin/test_chaindb_equivalence'
(which is the dedicated driver for chaindb_equivalence_tests)
rather than 'build/bin/test_triangles --run_test=chaindb_...'
(the test suite lives in a separate binary, not in test_triangles).
