debuginfod: extracted-from-archive file cache
Add a facility to service webapi and dwz/altdebug requests that
resolve to archives via a $TMPDIR file cache. This permits
instantaneous dwz resolution during -debuginfo rpm scanning, and also
instantanous duplicate webapi requests. The cache is limited both in
number of entries and in storage space. Heuristics provide
serviceable defaults.
