I do not follow: 

The smarthost transport is typically used by a machine without
permanent internet connection to deliver *to* a smarthost. This
smarthost the does the real delivery iusing M lookups et al.

google cares about the DKIM signature of the latter (the real mailserver).

OTOH if you want to use google as smarthost you need to use SMTP AUTH
instead of adding a DKIM signature on your personal PC/laptop.
