bitbake.conf: Add BB_TASK_NETWORK to enable task network globally

The NIS or icecc can't work when task network is dissable, add BB_TASK_NETWORK
to enable network globally for such exceptions.

Note, enable nscd on the build machine might be a solution, but that isn't
reliable since it depends on whether the network function has been cached or
not.
