force color use when MOCHA_COLORS is set to 'always'

[jaredly]

useful for an env that doesn't want to forkpty but still wants colored output.

env var likes this typically just check for any value for them to be on. e.g. MOCHA_COLORS=1 mocha test. and afaik, the process global object shouldn't need to be guarded.
