w1: don't allow arbitrary users to remove w1 devices

The search/pullup/add/remove device attributes were 0666 which would allow
arbitrary users to affect the 1 wire bus.  Change to 0664 to prevent that.

I found this patch in the Android tree, apparently this has never been
sent upstream so doing it now.
