Add dummy objc tools to Bazel for non-OSX target

As select statement requires to have all dependencies
resolved, we need to have all tooling of objc target
when doing a select if such targets are in the non
selected condition. This will enable to build
conditionally iOS targets only if we are on OS X.

This will permit to remove one of our hack from the
build.sh script of the tutorial.
