fuzz-introspector should show links to build logs

[evverx]

I took a look at https://storage.googleapis.com/oss-fuzz-introspector/systemd/inspector-report/20220421/fuzz_report.html and judging by

it was based on incomplete data (because systemd was most likely built without lto and gold) but I'm not sure why it's different from https://storage.googleapis.com/oss-fuzz-introspector/systemd/inspector-report/20220419/fuzz_report.html. I took a look at the latest build log and it appears the same CFLAGS were used to build those reports.

Anyway, it could be that I looked at the wrong build log or something like that so it would be great if instead of going to https://oss-fuzz-build-logs.storage.googleapis.com/index.html and guessing dates there fuzz-introspector showed links to the corresponding build logs right in the reports.

Looking at the size of the build logs

68M Apr 19 19:15 log-cdd966cb-78b1-4f8b-9f9a-5a3687140576.txt
4.8M Apr 21 03:12 log-cf3cc9a7-79d8-45e6-8ce4-67419987b326.txt

it appears the report at https://storage.googleapis.com/oss-fuzz-introspector/systemd/inspector-report/20220421/fuzz_report.html isn't complete and it should probably be the same as https://storage.googleapis.com/oss-fuzz-introspector/systemd/inspector-report/20220419/fuzz_report.html tomorrow. If it's the case I'm not sure why https://oss-fuzz-introspector.storage.googleapis.com/index.html points to incomplete reports like that.

I see how having a link to the full build log can be useful for the debug/test.
