Detailed description

This pr fixes the following debuginfod test timeout under -q (https://github.com/rizinorg/rizin/actions/runs/8939137806/job/24554607466?pr=4468#step:19:4628). Apparently if Rizin tasks are used, the debuginfod task sleeps and never wakes up even with the kill:

This is a cherry-pick from #4468.

Test plan

All builds are green.
