Build: Upgrade to go 1.12.9 (#18638)

* Build: Upgrade to go 1.12.9

* Build: Use default-mysql-client for debian buster

The go base image has been updated to use Debian Buster instead of
Stretch, which seems to have done away with mysql-client in favor of
default-mysql-client.

* Build: Update Dockerfile to use go 1.12.9

Fixes #18592
