Sage Weil d8d7113c35 udev: install disk/by-partuuid rules
Wheezy's udev (175-7.2) has broken rules for the /dev/disk/by-partuuid/
symlinks that ceph-disk relies on.  Install parallel rules that work.  On
new udev, this is harmless; old older udev, this will make life better.

Fixes: #4865

# this is a kludge installed by ceph to fix the /dev/disk/by-partuuid
# symlinks on systems with old udev (< 180). it's a stripped down
# version of a newer 60-persistent-storage.rules file that hopefully
# captures the same set of conditions for setting up those symlinks.
