Disable zlib-ng for the default cargo-install build (#354)

but explicitly enable it in our own builds.

This is because using zlib-ng sometimes does not compile easily on Windows,
and using the pure miniz_oxide offers a better install story from source.

For our binary builds, we can provide the optimal performance, and still
do that for most users as they will update with cargo-binstall, getting our
build as a second pass.
