macOS nightly fails to build with new libmagic from vcpkg

[jdblischak]

I synced my fork today, and the macOS nightly failed (even after a restart). It fails to install libmagic with vcpkg, which was just committed upstream about 8 hours ago in TileDB-Inc/TileDB@7753f33 (TileDB-Inc/TileDB#4673).

I assume the fix involves installing/updating autoconf/autotools with homebrew

I am getting this error when building with vcpkg in my local mac as well
