Disable fork_server for Node.js v0.10

:Release Notes:
The fork_server doesn't work properly with Node v0.10, so it's disabled.

:Detailed Notes:

The fork_server is incompatible with Node v0.10, so we need to disable
the init task that starts it. Something similar may come back in a
future build, depending on how other performance optimization turns
out.

:Testing Performed:
Built ipkg, installed, rebooted. No fork_server task started.

:QA Notes:
Should not cause any noticeable change in behavior.

:Issues Addressed:
[GF-2506] Upgrade Node.js to v0.10
