PACKER_HTTP_ADDR is unset for shell provisioner

[sparshev]

It seems the plugin forgets to set the PACKER_HTTP_IP (it's a standard interface of packer) so PACKER_HTTP_ADDR is left unpopulated. It's quite hard to pull any data from the host via standard packer's http server through shell provisioner without this env variable.
