Streamline project build.zig

Browse Source 
Offload as much work as possible into new `jetzigInit` function provided
by Jetzig's `build.zig`. This means that a new Jetzig project's
`build.zig` is now almost completely vanilla with the exception of two
extra lines:

```zig
const jetzig = @import("jetzig");
```

```zig
    try jetzig.jetzigInit(b, exe, .{});
```
