Fix chromium-driver for Debian 10+; Use firefox-esr instead of iceweasel (#19868)

* Since Debian Stretch, Iceweasel is as transitional package

Ref: https://wiki.debian.org/Firefox#Iceweasel

* chromedriver has been renamed to chromium-driver with Debian Stretch

Since Debian Buster, no transitional package for the old name is
provided anymore.
