two important patches from @stapelberg

• LoadInRelease: fail on unsigned data (with non-nil keyring) paultag/go-archive#12
• remove obsolete fallback: download InRelease for all suites paultag/go-archive#10

May have something to do with the nature of the CI runner image (perhaps it's ubuntu and we need the debian keyring?) but I haven't looked into this yet

[stapelberg]

Actually, the CI fails because our testdata contains an unsigned debian mirror :)

I’ll take care of it. Thanks for tagging the new release!
