user/node: Update to 16.19.0; fix test, NULL deref

* The worker-stdio test no longer raises RangeError on 32-bit Intel.

* The sigint test is no longer flaky (backported from 18 branch).

* The C++ Environment handler no longer segfaults when /proc is
  unmounted.  (Submitted upstream.)

Fixes: #795
