Fixed broken examples on Travis CI.

  * spec_helper.rb: Remove/Restore bundler files as default gems. It conflicts with some examples.
  * bundler/fetcher_spec.rb: Use dummy certification file instead of mock object. Because `File.read`
    was called with `bin/rspec` for gemspec loading.
  * support/buidlers.rb: An argument of `build_spec` conflicts some old versions of rubygems.
  * support/rubygems_ext.rb: Order gem dependency for Ruby 1.8.7-2.2.2
