update_engine: Make dd less verbose.

update_engine unit tests use the "dd" command for setting up some test
cases. By default, dd print the status of the operation on success.

This patch removes the status message reducing the unnecessary logs.

BUG=None
TEST=`FEATURES=test emerge-link update_engine`
