app-crypt/azure-keyvault-pkcs11: Bump to new pre-release for HSM support

[chewi]

Bump akv-pkcs11 to new pre-release for HSM support

We want to use HSM in Azure for added security. This pre-release includes all the renaming for Azure Key Vault.

How to use

From the SDK, install azure-cli and:

emerge azure-keyvault-pkcs11
export AZURE_KEYVAULT_URL="https://flatcar-sb-dev-kv.vault.azure.net/"
export PKCS11_MODULE_PATH="/usr/lib64/pkcs11/azure-keyvault-pkcs11.so"
export AZURE_KEYVAULT_PKCS11_DEBUG=1
SBSIGN_KEY="pkcs11:token=flatcar-dev-cert" # May be wrong, I don't have access.
p11-kit export-object --provider "${PKCS11_MODULE_PATH}" "${SBSIGN_KEY};type=cert" > cert.pem
sbsign --key "${SBSIGN_KEY}" --cert cert.pem some-grub-or-kernel-image

Testing done

@sayanchowdhury has manually tested this already. Testing it via CI would be awkward as we'd need to force the official build path and force the job onto Azure.

• Changelog entries added in the respective changelog/ directory (user-facing change, bug fix, security fix, update) -- N/A
• Inspected CI output for image differences: /boot and /usr size, packages, list files for any missing binaries, kernel modules, config files, kernel modules, etc.
