Update spec_helper to include 'chefspec/berkshelf'

This minor change allows you to run rspec outside of strainer while
still having cookbook dependencies automatically handled by berkshelf
(which also means you can run individual chefspec tests).

Note that this change does marginally increase the time it takes to run
a strainer test.

A similar change was recently accepted in the openstack-compute
cookbook.

Update the Gemfile to sync with latest Chef and ChefSpec.

Trying to keep all of the Gemfiles in sync so every cookbook has the same Gem
dependencies.
