Replace aging OpenPGP artifacts in the epg tests.

This replaces the old OpenPGPv4 key that is used in the test suite
with a more modern OpenPGPv4 key.  The key is the Alice key from
https://datatracker.ietf.org/doc/draft-bre-openpgp-samples/.  All
cryptographic artifacts in the test suite are updated accordingly.

Having old cryptographic artifacts in the test suite presents a
problem once the old algorithms are rejected by contemporary
implementations.
