XenAPI: specify block size for writing config drive.
When writing config drive, dd by default uses 512B as the block
size. It costs more than 3mins to write the 64M config drive.
It's longer than expected: Some health checking(fuel's heat
checking) on XenServer may failed due to timeout. So we need
improve the performance via specifying a bigger block size
with dd.
