It annoyed me for quite a while that running "journalctl --file=…" on a file that is not readable failed with a "File not found" error instead of a permission error. Let's fix that. We make this work by using the GLOB_NOCHECK flag for glob() which means that files are not accessible will be returned in the array as they are instead of being filtered away. This then means that our later attemps to open the files will fail cleanly with a good error message.
