kobject: kset_uevent_ops: make filter() callback take a const *

The filter() callback in struct kset_uevent_ops does not modify the
kobject passed into it, so make the pointer const to enforce this
restriction.  When doing so, fix up all existing filter() callbacks to
have the correct signature to preserve the build.
