udev: static nodes - fix default permissions if no rules is given

udev: static nodes - fix default permissions if no rules is given

<falconindy> kay: just curious -- it looks like nodes created by udev from
  modules.devname all have 000 perms, and there's nothing in udev that attempts
  to change this. is it intended?

<kay> falconindy: we might miss the default of 0600
<falconindy> seems like it
<kay> falconindy: stuff that has a rule works i guess
<kay> falconindy: i'll add the 0600 now
