[PATCH v2] udev: behave like 80-drivers.rules

[Tom Gundersen]

 1) Apply the rules also to 'change' events. This should do no harm
    and makes sure that the rules are run whenever the 80-drivers.rules
    are.
 2) Don't try to load modules when a driver is already loaded.
 3) Always apply blacklisting.

v2: don't convert modprobe to the builtin kmod. This can be done once
    udev>=176 is more widespread.
