* Update to 6.8.3
* Switch to the Darwin distribution instead of the Linux one since files
like node_modules/x-pack/plugins/reporting/server/browsers/chromium/paths.js
have platform specifications and in the Darwin distribution that includes
FreeBSD (not so for the Linux one).
* Depend on node 10, which is the version distributed with 6.8.3
* Improve pkg-deinstall by indicating how to permanently delete data
