bridge other build logs to our tinderbox page

[Caolán McNamara]

LibreOffice is also continuously built now in a (somewhat bizarro)
configuration by oss-fuzz, here's the build log from there
https://oss-fuzz-build-logs.storage.googleapis.com/build_logs/libreoffi
ce/latest.txt

It'd be nice to get that build status and log on the same page as the
rest of our builds. What are my best options to get that working ?
