system_profile does not use included templates.

[rbclark]

Currently if you add the following code to a cookbook which has the system cookbook as a dependency

system_profile '/etc/profile' do
  path ['/usr/local/prgm/bin']
end

Then you receive the following error:

ERROR: template[/etc/profile] (/tmp/vagrant-chef/42964f892d0bdc1f3523934e6c16f380/cookbooks/system/providers/profile.rb line 21) had an error:    
Chef::Exceptions::FileNotFound: Cookbook 'prgm-chef' (0.1.0) does not contain a file at any of these locations:
==> default:   templates/centos-6.7/profile.erb
==> default:   templates/centos/profile.erb
==> default:   templates/default/profile.erb
==> default:   templates/profile.erb

This pull request fixes this by explicitly specifying that the template is located in the system cookbook.
