[TIMOB-24160] Hyperloop: iOS - Exclude CocoaPods products from being removed

In TIMOB-24057 the output directory for built CocoaPods products was changed. This introduced a regression with sequential builds. The build.ios.removeFiles hook deletes files from the iOS build directory that were not previously unmarked with unmarkBuildDirFile. The CocoaPods libraries need to be explicitly unmarked so they won't get deleted during this hook. *Steps to reproduce the behavior* 1. Create a new Hyperloop enabled project or use the hyperloop-examples project 2. Make sure the build dir is clean by either deleting it or running appc ti clean 3. Build the project with appc run -p ios 4. Re-run the build again *Expected behavior* Able to successfully run subsequent builds *Actual behavior* The build fails due to missing libraries during linking
