child_process.fork: don't modify args

[koichik]

Because child_process.fork() modify args argument, the worker processes after the second cannot get right arguments with cluster.
example:

a.js

console.log(process.env.NODE_WORKER_ID, process.argv);

result:

$ node cluster a.js foo bar
Detected 2 cpus
Worker 5097 online
Worker 5098 online
1 [ '/home/koichik/git/joyent/node/out/Release/node',
  '/tmp/a.js',
  'foo',
  'bar' ]
2 [ '/home/koichik/git/joyent/node/out/Release/node',
  '/tmp/a.js',
  '/tmp/a.js',
  'foo',
  'bar' ]
