Update to latest zig and simplify build.zig

[freakmangd]

• installHeader's signature was changed recently, so a versioned function was added for it
• srcdir isn't needed, just adding "src/" before each path is sufficient
• cabarger's hack seems to not be needed anymore
• process.Child.run and process.Child.exec was coerced into a single function

Tested on ubuntu x64, on both 0.12.0-dev.3580+e204a6edb and 0.11.0

@freakmangd I'm not an expert on Zig building but it looks good to me. Thanks for the review!

This breaks #3834 again

[raysan5]

@freakmangd please, could you review this issue?

[freakmangd]

@sykire Hi, sorry about the breakage, I neglected to test building raylib as a local dependency, I'll get that working asap

[freakmangd]

@sykire Could you try using #3913 and let me know if it resolves your issue? Thanks!

It builds successfully using zig build although if I do zig build run. It follows with:

I think that's due to an unrelated thing. I'm new to zig and raylib so don't much about them.

I'm using the configuration from this site: https://siddharthroy.com/posts/how-to-use-raylib-with-zig-without-any-bindings

P.D. This is what is has showing before when doing zig build

@sykire I'm using the same configuration to build and run raylib in my testing. Were you able to build and run it before this PR was merged?

Maybe try installing the required libraries for your system if you haven't: https://github.com/raysan5/raylib/wiki/Working-on-GNU-Linux I'd think it'd break during the build process if you don't have X11, but I could be wrong

Edit: Looks like you're getting a GLFW_PLATFORM_ERROR https://www.glfw.org/docs/latest/group__errors.html

[sykire]

I couldn't build it, I got until the error in the ticket #3834 because of failed path resolution that was solved but then regressed. The other error I think I'm missing to build some library. I'm still in the process of running Raylib + Zig successfully once 😅.
