fix(build): build.zig: use luajit for windows

These were disabled as they failed when tested with cross-compiling,
but it works fine for windows natively on ci, so let's use that.

mac os builds after disabling debug info, which currently
triggers a bug in zig's MachO linker: natecraddock/ziglua#191
Tracking issue: https://codeberg.org/ziglang/zig/issues/30669
Unfortunately actually using the JIT of luajit still triggers
issues on mac os, so we cannot use it yet.

Also sync luajit version used via ziglua to a recent one
like we use in cmake, see natecraddock/ziglua#196
