[PATCH] add options to udevtrigger to control scanning

[Greg KH <greg@kroah.com>]

This patch has been in the gentoo tree for a bit.  It modifies
udevtrigger to allow a little more fine grained control for people who
don't want all of the sysfs tree to be scanned by udevtrigger at
startup.

Patch was originally written by Martin Schlemmer <azarah@gentoo.org> but
was forward-ported by me to the latest version of udev.
