Previously, the size of the debuginfod cache would grow without bound. This change prunes the cache after a successful debuginfod lookup, as is done in libdebuginfod. The cache pruning behavior is configured by a new DEBUGINFOD_CACHE_POLICY environment variable. The semantics of this are the same as --thinlto_cache_policy.
