ci: fix integration + bundle jobs on their first GitHub run

These two jobs moved from the old Gitea runner and ran for the first time on
GitHub ubuntu-latest in this branch's test workflow; both failed on
environment differences, not on product regressions.

integration_test: the GitHub runner exposes BOTH a `linux` desktop and a
`chrome` web device, so a bare `flutter test integration_test/...` aborts
with "More than one device connected" before compiling. The Gitea runner /
dev box only had the one device, so it was latent. Pin `-d linux` in
ci/test_integration.sh. Verified locally: the full suite boots and passes.

smoke-bundle: the `smoke-bundle` make target was the only test target
missing the `gen-build-info` prerequisite, so build_info.g.dart was absent
and the release build failed to compile (clideVersion/clideCommit/clideName/
clideTagline/... undefined). Add the prereq. Verified locally: the release
bundle now builds (`✓ Built .../release/bundle/clide`); the xvfb run step is
CI-only.
