Wait for operation to complete when writing to SD card
The actual data transfer does not complete when the 'dd' operation
exits. Pulling out the removable media too soon causes corruption.
Make sure the utility waits till data is synced.
BUG=None
TEST=manual
. used cros_write_firmware to put an image to the SD card
