Configure the nodejs build to use os CA store

[grahamaj]

This issue is a request to update node and build it with the new flag --use-openssl-ca to use openssl's certificate store

Explaination
The default behavior for Nodejs is to bundle a snapshot of Mozilla CA (certificate authority) store into the build. This means that the default CA store is fixed upon building node. This is also not very helpful for non standard CA's.

As of Node 7.5.0 and the future release 6.11.0 node can be built to use openssl's certificate store

From node's build script readme file:

Using OpenSSL store allows for external modifications of the store. For most
Linux and BSD distributions, this store is maintained by the distribution
maintainers and system administrators. OpenSSL CA store location is dependent on
configuration of the OpenSSL library but this can be altered at runtime using
environmental variables.

Node 6.11.0 proposal including the fix for the LTS verison: node pull 13059

I discussed this with @grahamaj today -- we'll put this off until the next release of externpro

@smanders This may be a noop. It appears that we might be able to use a command line argument at runtime rather than specifying it at build time. See https://nodejs.org/dist/latest-v6.x/docs/api/cli.html#cli_use_openssl_ca_use_bundled_ca

removed "update" label since we now build v6.11.4 which has this feature (if we need to modify the build) -- when this issue was first written we needed to update to at least 6.11.0 and then add the enhancement

@grahamaj please let me know if we need to consider doing this in the future... for now I'm closing this issue as "won't fix" - thanks!
