Allow kotlin modules to skip packaging the kotlin stdlib

Host tools like lint may package their own version of the kotlin
stdlib, and any jars loaded by them shouldn't contain the platform
version.  Add a static_kotlin_stdlib property that defaults to true
to allow building the module without staticalling including the kotlin
stdlib.
