nixos/test-driver: highlight driver log lines
There is a whole lot of noise in a NixOS test log due to journal,
commands, and test driver messages all being mixing together.
With this commit the test driver messages are highlighted so you don't
have to squint too much to see where a subtest starts and ends or what
was the last command being run.

Here's an excerpt from a highlighted log:
