Fix cached-module-box cache keys

Browse source 
* module/language/cps/reify-primitives.scm (cached-module-box): Include
public? in cache key, so we don't accidentally alias private and
exported names.  Also include bound?, to avoid a window in which thread
A resolves and caches var V in preparation for setting it, but thread B
sees V for ref before it was initialized.
