Update the v0.10 CA certificates to match the CA certificates in v0.11

I was hitting a SSL certificate validation issue when using node v0.10 when I realized that the latest Go Daddy root certificates were not including the v0.10.  It looks like this issue was covered in joyent/node#6489 and joyent/node#6013, but those changes are only in the v0.11 branch.

I've pulled the related changes from v0.11 and merged them into the v0.10 branch.  Is it possible to get the updates included in v0.10?
