Wait for the kernel and udev to settle partitions for a second time (#790418)

There is still another subtle issue.  When GParted_Core::commit() closes
the device, the kernel initiates a second set of events which removes
and re-adds the partitions again.  Need to wait for these to complete
to prevent any following step failing with missing partition device
nodes.

Bug 790418 - "Unable to inform the kernel of the change" message may
             lead to corrupted partition table
