solver pulls in gpgv-from-sq unexpectedly

[Christian Ehrhardt]

As reported on bug 2111790 gpgv-from-sq was pulled in.
Julian said to cerate a new bug for this aspect [1].

This here is that bug.

Original behavior

```
$ sudo apt upgrade
The following packages were automatically installed and are no longer required:
  gpgv-from-sq gpgv-sq
Use 'sudo apt autoremove' to remove them.

Upgrading:
  bind9-dnsutils cron-daemon-common gpgv libc6 libglib2.0-bin libpam-modules-bin libpython3.13-minimal open-iscsi screen
  bind9-host gcc-14-base libatomic1 libc6-dev libglib2.0-data libpam-runtime libpython3.13-stdlib python3.13 sysvinit-utils
  bind9-libs gcc-15-base libc-bin libgcc-s1 libopeniscsiusr libpam0g libstdc++6 python3.13-gdbm
  cron gir1.2-glib-2.0 libc-dev-bin libglib2.0-0t64 libpam-modules libpython3.13 locales python3.13-minimal

Installing dependencies:
  gpgv-from-sq gpgv-sq

Suggested packages:
  gpg-from-sq sq

Not upgrading:
  dirmngr gnupg gnupg-l10n gnupg-utils gpg gpg-agent gpg-wks-client gpgconf gpgsm

```

But with dist-upgrade it instead is

```
$ sudo apt dist-upgrade
Upgrading:
  bind9-dnsutils dirmngr gnupg-l10n gpgconf libc-dev-bin libglib2.0-bin libpam-runtime libstdc++6 python3.13-minimal
  bind9-host gcc-14-base gnupg-utils gpgsm libc6 libglib2.0-data libpam0g locales screen
  bind9-libs gcc-15-base gpg gpgv libc6-dev libopeniscsiusr libpython3.13 open-iscsi sysvinit-utils
  cron gir1.2-glib-2.0 gpg-agent libatomic1 libgcc-s1 libpam-modules libpython3.13-minimal python3.13
  cron-daemon-common gnupg gpg-wks-client libc-bin libglib2.0-0t64 libpam-modules-bin libpython3.13-stdlib python3.13-gdbm

After a short confusion I was able to go on:

@Julian Andres Klode with --solver internal it resolves it differently
that one would not pull in gpgv-from-sq gpgv-sq - how do you want your logs taken then?

Julian Andres Klode
yes that's expected, the dump it creates is correct though
I forgot to fix the bug that allows dumping to work if 3.0 is set

---

This is the full output of the run:

```
$ sudo apt upgrade --solver internal -o Dir::Log::Solver=/tmp/log.edsp.xz
The following package was automatically installed and is no longer required:
  gnupg-l10n
Use 'sudo apt autoremove' to remove it.

Get resolved to:
