remove RCT_FOLLY

[billnbell3]

This means @candlefinance/faster-image DOES declare RCT-Folly as a dependency in its podspec, and it's incompatible with React Native's precompiled builds (RCT_USE_PREBUILT_RNCORE=1).

[billnbell3]

Please remove RCT_FOLLY dependency in podspec so we can all use precompiled builds.

• s.dependency "RCT-Folly"
  30 + # Only depend on RCT-Folly if not using precompiled builds
  31 + if ENV['RCT_USE_PREBUILT_RNCORE'] != '1'
  32 + s.dependency "RCT-Folly"
  33 + end
