Since it's not so easy to encrypt a message exactly the same way twice, we
only verify if the message has been encrypted or not.
Introduce minor changes to the library itself, because it doesn't work very
well with modern GnuPG.
Also, include GnuPG directory (pointed at by --homedir option).
- Use an environment variable to point at the configuration file while
strating gpg-mailgate.py.
- Unify paths: store temporary config, logs and anything else under 'test'
directory.
- Configure more tests (RSA, Ed25519).
- Add test descriptions to be shown before they're started.
