[$] Enabling debuginfod for Fedora by default

In early April, Fedora program manager Ben Cotton posteda proposal to use the distribution'sdebuginfodservers by default in Fedora 35. This feature would help developerswho are trying to debug or trace their programs using various tools, but who arelacking the source code and debugging symbols needed. The serverscan provide that data directly to the tools as needed, but there are somesecurity and privacy concerns to work through before turning the feature onby default.
