Avoid calling Array.prototype.join() in debug() calls. These are evaluated on every call, even if the debug() call is a no-op. This commit replaces the join() calls with the %j placeholder.

As a general note, we should probably migrate the codebase to using printf() style placeholders, and avoid template strings and string concatenation in debug() calls. It might be a good Code and Learn activity. The http2 module is a particularly bad offender.

Checklist
  • make -j4 test (UNIX), or vcbuild test (Windows) passes
  • commit message follows commit guidelines

❤️ I am definitely 👍 on that.

I think template strings are a lot more JavaScript-y than printf-style replacement, so I would be against doing this in places where it's not causing runtime overhead.
