[OE-core] [PATCH 2/8] mdadm: add udev rules to create by-partuuid for MD devices

[Liwei Song]

installer use partuuid for boot and swap partition,
But the udev rules for MD devices do not have rules to create
by-partuuid under /dev/disk/, this will take 90s to wait until failed
add the rules to create by-partuuid to support boot from raid
disk with "root=PARTUUID=XXX"
