Upgrade google-auth from 1.4.1 -> 1.20.1.

BUG=chromium:1131686
TEST=sudo emerge google-auth inside chroot

To generate the manifest file, ran this inside chroot, in the
google-auth dir:

 ebuild google-auth-1.20.1.ebuild manifest

Chose 1.20.1 (and not newer version) because this is newest in portage
overlay, and we need at least 1.19.0 for google-cloud-logging.
