debuginfod: rework threading model for file/archive scanning
We switch from a thread per supplied PATH, with a semaphore based concurrency control, to a fixed number of worker threads collecting the result of a plain directory traversal being put into a work queue. This allows maximal continuous concurrency, even if the PATH directories are dramatically differently sized. There is no more need to use concurrency-motivated subdirectory wildcards for PATH entries: just a single top level directory will work fast. doc & tests incl.
