fix HTTPS downloads by service on webOS 5+

By default, Node.js uses its builtin certificate store, which is
outdated on webOS. Node.js v7.5.0 added the --use-openssl-ca command
line option, and the additional options are read from the NODE_OPTIONS
environment variable since v8.0.0. Therefore we can make node use the
OpenSSL certificate store for services run with our run-js-service on
webOS 5 (which uses v8.12.0) and newer by setting NODE_OPTIONS.
