Don't load class cache and bootstrap file on php 7

As discussed in symfony/symfony#20668, the class cache features should be deprecated. Since the class cache and the bootstrap file are still useful on php 5, we load them only when running on php 5.

A future php-7-only release of Symfony Standard should remove those blocks completely.
