debuginfod: debuginfod client should cache negative results.
Add debuginfod_config_cache for reading and writing to cache
configuration files, make use of the function within
debuginfod_clean_cache and debuginfod_query_server.
In debuginfod_query_server, create 000-permission file on failed
queries. Before querying each BUILDID, if corresponding 000 file
detected, compare its stat mtime with parameter from
.cache/cache_miss_s. If mtime is fresher, then return ENOENT and
exit; otherwise unlink the 000 file and proceed to a new query.
tests: add test in run-debuginfod-find.sh
test if the 000 file is created on failed query; if querying the
same failed BUILDID, whether the query should proceed without
going through server; set the cache_miss_s to 0 and query the same
buildid, and this time should go through the server.
