[Feat] Avoid installing Flipper in CI

[cipolleschi]

Summary

This PR speeds up the build in CircleCI by avoiding adding Flipper dependency when running in CI.

The savings are:

• ~ 13/15% for test_ios
• ~ 30/40% for test_rntester
• 50% for test_ios_template

Edit after review: We do actually want to have Flipper in the test_ios_template to check that it builds correctly.

Changelog

[iOS] [Changed] - Do not add Flipper when running in CI.

Just a heads up that this would reduce our confidence on having Flipper working on the new app template. I'm not sure we want to do this.

On Android, we always include Flipper regardless of CI.

I can understand the win on build time for a RN user, but as we're testing the default template here, it probably makes sense to make sure Flipper is also included in the build
