The Windows ARM builders on EC2 run on qemu via KVM. We use a userspace
network device for simplicity, which also conveniently restricts which
ports are exposed. In order to make a request to the metatadata service,
which is routed in a different way than the public internet, we
explicitly forward the port to the guest VM on a special ip/port.
This introduces a hard-coded value for Windows ARM64 buildlets. We
should be able to improve this code to detect it, but this will get the
buildlet unblocked.
The buildlet image also includes llvm-arm64 mingw rather than a gcc
based distribution. This change also adds the correct directory to the
path.
