prefer native arch over higher priority for providers
The rational from the buglog:
> The problem here is that the Priority field in one of the Packages files
> is incorrect due to a mishap with reprepro configuration, […] the
> amd64 version is Priority: standard but the arm64 version is Priority:
> optional (and has a stray "optional: interpreters" field).
> […]
> However, Priority is a rather weak property of a package because it's
> typically applied via overrides, and it's easy for maintainers of
> third-party repositories to misconfigure them so that overrides aren't
> applied correctly. It shouldn't be ranked ahead of choosing packages
> from the native architecture. In this case, I have no user-mode
> emulation for arm64 set up, so choosing m4:arm64 simply won't work.
This effectly makes the priority the least interesting data point in
chosing a provider, which is in line with the other checks we have
already order above priority in the past and also has a certain appeal by
the soft irony it provides.
Closes: #718482
