This pulls in a change from github.com/tailscale/QDK to verify code signing
when using QNAP_SIGNING_SCRIPT.
It also upgrades to the latest Google Cloud PKCS#11 library, and reorders
the Dockerfile to allow for more efficient future upgrades to the included QDK.

QNAP now requires builds to be signed with an HSM.
This removes support for signing with a local keypair.
This adds support for signing with a Google Cloud hosted key.
The key should be an RSA key with protection level `HSM` and that uses PSS padding and a SHA256 digest.
The GCloud project, keyring and key name are passed in as command-line arguments.
The GCloud credentials and the PEM signing certificate are passed in as Base64-encoded command-line arguments.
