ci : add FRAMEWORK_FOLDER_PATH to xcodebuild command

This commit adds FRAMEWORK_FOLDER_PATH to xcodebuild command in the
xcodebuild commands so that the framwork can be found.

It also removes the installing of llama.cpp to the system as that is not
needed anymore and the xcodebuild/xcode builds will use the framework
instead.
