zig-build: lazyPath fixes

[kassane]

Minor fix: lazyPath

b.path("path") - get src/subpath contents - not allow abspath
old .{ .path = "path" } was renamed to .{ .cwd_relative = "abspath" } - for external path.

Works on zig version: v0.12.0 (optional change), v0.12.1, v0.13.0 & v0.14.0-dev (currently master);

Note: old zig version generate zig-cache, but v013.0 and master rename to .zig-cache!

Extra update: replacing zlib-master to release-version

$ zig fetch --save=zlib git+https://github.com/madler/zlib#v1.3.1
info: resolved ref 'v1.3.1' to commit 51b7f2abdade71cd9bb0e7a373ef2610ec6f9daf
warning: overwriting existing dependency named 'zlib'

Why switch zig-ci host?

The default GH-actions is arm64-macos runner. However the error that occurred may have been confused with x86_64.

CI - macos: https://github.com/kassane/libxlsxwriter/actions/runs/10831257972/job/30052830154
