errors: create internal connResetException

Replace various instances of errors that use code ECONNRESET with a
single centralized factory function to create the errors.

(While making changes to _tls_wrap.js, this also takes the opportunity
to make trailing commas consistent on multi-line arrays. One had a
trailing comma and one didn't. This adds a traiiling comma to the one
that didn't.)
