Add a few more unittest targets to chromiumos_preflight group.

Uprevs are blocked due to a broken test target that gets built in
the ebuild but not Chrome's CQ.

This updates the chromiumos_preflight group to include all binaries
listed in:
https://source.chromium.org/chromiumos/chromiumos/codesearch/+/master:src/third_party/chromiumos-overlay/chromeos-base/chrome-binary-tests/chrome-binary-tests-0.0.1.ebuild

Needs crrev.com/c/2125027 before this can land.
