[ Reason ]
Bug #1037435. Some tests try to use the network.
Also, we need to disable some tests as flaky.
[ Impact ]
Package FTBFS 100% of the time when built using the schroot backend
of sbuild, which was the default in bookworm.
[ Tests ]
I've tested that the package builds ok again. I've also tested
that the failure rate after disabling flaky tests has been
greatly reduced.
[ Risks ]
Very low. No code changes. Some tests are disabled and some other
tests have a relaxed threshold so that they do not fail so easily.
