Prober: no packaging or release-name-plus-extension as inner name

Lone candidates are often par2 volumes of random-named sets
("42507096….vol007+08.par2"): their yEnc name was taken as the inner
name. Packaging names are skipped for lone files too, and a name that
starts with the release's own name says nothing new.
