Bug#549298: mdadm should copy its own rules file to the initramfs

[Petter Reinholdtsen]

tags 549298 + patch
thanks

I had a look in udev and mdadm, and suspect this untested patch will
solve the problem.  It is a copy of code found in udev with only the
mdadm rule left in the for loop.

I do not know the inner workings of udev and mdadm, so I am not sure
if this was the change the udev maintainer Marco d'Itri had in mind.
Cc to him, hoping for feedback on the approach.
