vdirsyncer: enable synchronization with google

Hi porters,

with this additional dependency vdirsyncer is able to synchronize
contacts and calendars with google.

The setup is a bit annoying since you need to register your vidrisyncr
instance with Google to get an oauth id and secret. The needed steps can
be found here:
https://vdirsyncer.pimutils.org/en/stable/config.html#google.

OK?

Remi
