chromium: fix increased build time for non-cross-compilation builds

Browse Source 
Having

```nix
host_toolchain = "//build/toolchain/linux/unbundle:host";
v8_snapshot_toolchain = "//build/toolchain/linux/unbundle:host";
```

on native, non-cross-compilation builds roughly doubles the build steps
and, by proxy, compute and time needed to build.

So to resolve this, we conditionally change those values depending on
whether we are cross-compiling or not.
