fix zig master build.zig

[AndrewKraevskii]

ziglang/zig#20388 broke build.zig so new hack should be made :(

[floooh]

Hmm, looks very hacky indeed :)

I'd link to understand the change in the Zig build system first before merging, maybe I can think of a different way.

[floooh]

Ok, I'll merge the PR but will try to come up with a different way to detect when the new code path is needed, maybe checking the major Zig version is enough (e.g. assuming that everybody who's on 14.x is on the bleeding edge anyway).

[floooh]

Hmm there's something else broken since the Emscripten build doesn't link against the sokol C library anymore. Investigating...

[floooh]

Hmm ok, looks like lib_main.getCompileDependencies(false); is not a drop-in replacement for lib_main.root_module.iterateDependencies(options.lib_main, false);... investigating...

[floooh]

Ok, this seems to work (also much simpler than before):

...I'll test with pacman.zig next.

PS: thanks for the PR (also looking into your dcimgui PR next).
