No longer use modprobe-wrapper, that should fix bug 191813 and other breakages caused by our wrapper. This also removes auto-blacklisting of modules that get loaded by modules.autoload. It will break blacklisting of some special aliased modules like pcspkr until bug 192201 is fixed. Now also run persistent-net rules when coldplug is disabled, bug 191466.
