My goal is just to ensure that we use Lit builtin commands exclusively whenever possible so as to decouple our test suite from the underlying platform as much as possible. `true` is not a Lit builtin but we have a Lit builtin equivalent (`:`), so this patch seems desirable. I'll go ahead and merge this but I agree it'd be interesting to figure out how these tests manage to work on Windows.
