[PATCH v3] g10: be --quiet about weak digests & rejected third-party key signatures

[Robin H. Johnson]

Let --quiet hide the output about weak digests and rejected third-party
key signatures.
```
gpg: Note: third-party key signatures using the %s algorithm are rejected
Note: signatures using the %s algorithm are rejected
```

This does not change actual behavior, it just omits the notes instead.
This is primarily intended to be used in automation.
