Remove global state from sysprop libraries

Browse Source 
Sysprop libraries use a global list to rewrite dependencies from
implementation libraries to public stub libraries when appropriate.
Remove the global list, and instead add a dependency from the
implementation to the public stub that forwards the JavaInfo.
