Build native QEMU from the third_party/qemu submodule

Browse Source 
Native and wasm now share one source tree, so the xteink machine and SD
fixes never diverge. scripts/build-qemu.sh configures a dedicated
build-native/ dir (ucontext coroutine backend; the fork defaults to the
wasm fiber backend) that never clobbers the Emscripten build/ config.
Retires the separate _scratch/qemu-src patch-based native build.
