>=0.10 engines claim is (probably) no longer accurate

[cburroughs]

Currently package.json states:

    "engines": {
        "node": ">=0.10"
}

When I try to npm install with v0.10.48 I get

It's possible that node-manta still works in some cases, but given the test tools are among the above errors, it is hard to be confident in that.

I'm unsure what a better value would be, or how long this library needs to continue to support EOL nodejs versions.

FWIW, I believe we still use this package with Node v0.10 in a number of places. Sadly, much of Manta is still on 0.10.

If it's no longer accurate, we should update https://github.com/joyent/node-manta/#supported-nodejs-versions, which looks like it was last updated under #318 in August, 2017.
