Color diff output in tests/functional/lang tests

Use `diff --color=always` to print colored output for language test
failures. I've also flipped the arguments so that expected lines missing
from the actual output will be marked with a red `-` and additional
lines found in the actual output will be marked with a green `+`.
Previously it was the other way around, which was very confusing.
