Subject: [PATCH] cloud-utils: Make growpart not rely on udevadm

Version 0.32 of cloud-utils added a call to "udevadm settle" in growpart,
so adding a dependancy on eudev to the cloud-utils-growpart package. This
patch enables growpart to run without requiring eudev so that it can be
used on mdev-based systems also.
