Update lang/nodejs4 to 4.8.5.

zlib:
- CVE-2017-14919 - In zlib v1.2.9, a change was made that causes an
  error to be raised when a raw deflate stream is initialized with
  windowBits set to 8. On some versions this crashes Node and you cannot
  recover from it, while on some versions it throws an exception.
  Node.js will now gracefully set windowBits to 9 replicating the legacy
  behavior to avoid a DOS vector.
