Per suggestion from Vladimir, eliminate check_wildcard_match(), which
was only being used by insmod these days. Also, I spent a minute adjusting insmod so that it first searches /lib/modules/`uname -r` and then (if that fails) searches /lib/modules, which makes bb insmod behave much more like the real insmod, and should avoid nasty surprises (such as the recent "Modutils vs. Busybox..." thread). -Erik
