Fix the bug of filtering out filename too early, before we know the
program name, if using unified file-or-prog filter (i.e., -f
<any-glob>). Because we try to filter BPF object file early without
opening and parsing it, if any_glob (file-or-prog) filter is used we
have to accept any filename just to get program name, which might match
any_glob.
