toaster: add Selenium Docker container as browser test driver option

Once again, some random upgrade on one of my build servers prevented me from running the selenium browser tests. Ugh!

So, this patch will allow you to run the standard tests using the Selenium docker container as the driver rather than relying on what seem to me to be pretty brittle drivers for firefox or chrome.

The README in lib/toaster/tests/browser has some instructions and more are located on the wiki at https://wiki.yoctoproject.org/wiki/Running_Toaster_Tests_with_Containers

This patch assumes the firefox container. Later, if we want to, we can add an additional env variable to override firefox or chrome containers. Initially, I just wanted to get this approach working so that we could use it.
