futility: updater: Revise output messages for debug logs

In auto update and recovery, the firmware updater was executed with both
stdout and stderr logged. However, the logs usually comes with all stderr
first then all stdout. This makes it harder to debug because the
messages logged in out of order.

TO solve that, few macros are introduced:
 INFO: for useful information.
 STATUS: the most common information, usually comes with a prefix code.

And all messages should now go to stderr except the final execution
result (and those output commands, for example --manifest).
