The SigSpoof vulnerability found in GnuPG also affects Monkeysign, but
in a lesser way. We check signatures only in one place: when we import
images. This is a corner use case that is probably quite uncommon and
since it requires access to the file in itself, it's likely there are
already other ways to import arbitrary signatures into monkeysign.

Still, we play it safe and disable the "verbose" mode that can
possibly be enabled in `gnupg.conf` as recommended by the reporter,
Marcus Brinkmann.

false isn't defined, that must be False

we would previously copy the gpg.conf to the temporary keyring, which
works, but then when we actually sign the key, we iterate over the
secrets to figure out which key to use, and then the default-key
setting is ignored.

instead, we simply parse the gpg.conf by hand to detect the
setting. we could have used gpgconf, but this doesn't seem easier to
parse and adds yet another dependency. i would argue it is easier and
simpler to parse the config file than to shell out to yet another
obscure gpg command.

this is a finalization of #721599
