gpg: Prefer SHA-512 and SHA-384 in personal-digest-preferences.

* g10/keygen.c (keygen_set_std_prefs): prefer SHA-512
and SHA-384 by default.

In 8ede3ae29a39641a2f98ad9a4cf61ea99085a892, upstream changed the
defaults for --default-preference-list to advertise a preference for
SHA-512, without touching --personal-digest-preferences.  This makes
the same change for --personal-digest-preferences, since every modern
OpenPGP library supports them all.
