Move bolts dependencies to Fresco plugin (#1937)

Summary:
Fixes https://github.com/facebook/flipper/issues/1919

Somehow the diff author put the dependencies in the root `build.gradle`, which is unnecessary as this is only used by Fresco.

Pull Request resolved: https://github.com/facebook/flipper/pull/1937

Test Plan:
Built the sample app, checked that the Fresco stuff continues to work.
