Bug 25435: use --no-auto-check-trustdb to avoid modifying gpg keyring files

By default gpg will from time to time update its trust database. When
this happens it will also modify the keyring files to add some trust
information. To avoid this we add the --no-auto-check-trustdb option.

As we don't use the Web of Trust when we use a keyring file, we also
disable it using `--trust-model always`.
