actix-web eventually depends on actix-connect 1.0.2
actix-connect 1.0.2 depends on prerelease trust-dns-resolver 0.18.0-alpha.2,
which declares broken deps on trust-dns-proto "0.18.0" - should be "=0.18.0-alpha.2"

debcargo doesn't support prerelease versions because semver compatibility
doesn't apply. So patching trust-dns-resolver to fix their bug is not an
option for us here. So just disable actix-web 2 here.
