services/device/device: Retry upload when already exists

If we try to upload the same binary twice within the same second, the
second attempt will use the same object name and then fail with an
"already exists" error.

There are many ways to fix this problem:
 - We could ignore this error and assume that it is indeed the same
   binary and we don't need to upload it again.
 - We could change the timestamp to have finer granularity.
 - We could retry with a slightly different object name.

This change implements the third option.
