Fix build.zig

[cedeon]

I can only get zig to build raylib if I do this + move the file to the parent directory.

I can only get zig to build raylib if I do this + move the file to the parent directory.

1. Did you get the latest changes from master branch?
2. What platform are you building on?
3. Is the issue building or using it after building?

I tried this and it worked perfectly (linux x64, zig 0.13.0):

git clone git@github.com:raysan5/raylib.git
cd raylib
zig build

I'm having the same issues with the latest commit on Linux, using the addRaylib function with the Zig package manager.

Seems to be introduced by #4358 where it caused a mismatch between the fields of Options and the expected fields inside the logic of addRaylib.

raylib/src/build.zig

Line 27 in 4050b55

.platform_drm = options.platform_drm,

raylib/src/build.zig

Line 300 in 4050b55

platform: PlatformBackend = .glfw,

How to reproduce:

1. Start a new Zig project with zig init.
2. Add a sufficiently new version of Raylib as a dependency with zig fetch --save=raylib https://github.com/raysan5/raylib/archive/3fb1ba25aca0a6b023ca254a0910df36b0744e64.tar.gz
3. Add the following lines inside the build function of build.zig:

    const raylib = @import("raylib");
    const raylib_lib = try raylib.addRaylib(b, target, optimize, .{});

4. Run zig build to get the following output:

$ zig build

I also needed the following patch to get it building:

The orelse null is redundant so I removed that. It seems like b.dependencyFromBuildZig doesn't support ?[]const u8 (the type of options.config) so I commented it out. Doing something like orelse "" caused some other errors. I have no idea if this approach is correct though.

@cedeon @CrackedPixel @sagehane Thanks for reporting! Please note that I don't maintain the build.zig so I usually trust Zig experienced users sending PRs.
