security/sequoia-sq: update to 0.34.0

Notable changes
  - `sq` now uses `sequoia-keystore` for secret key operations.

    When decrypting a message, `sq` will automatically ask the
    keystore to decrypt the message.  `sq sign --signer-key` can be
    used to specify a signing key managed by the key store.

  - New top-level option: `sq --no-key-store`: A new switch to
    disable the use of the key store.

  - New top-level option: `sq --key-store`: A new option to use an
    alternate key store.

  - New subcommand `sq key list` to list keys managed by the key
    store.

  - New subcommand `sq key import` to import a key into the key
    store.

  - When showing a user ID for a certificate, choose the one that is
    most authenticated.
