Give up brew update on Travis

No `brew update` causes "Error: Your Homebrew is outdated" like https://travis-ci.org/ruby/ruby/jobs/547485832, but doing `brew update` is also problematic like https://travis-ci.org/ruby/ruby/jobs/564916879. Hoping that the former case is more rare, let's try no `brew update` again.
