PR11246 cont'd: Separate script/stapconf caching

I'm separating the caching and creation logic for stapconf, so it can be
conditionalized on s.use_cache instead of s.use_script_cache.

* session.h (systemtap_session): Store base_hash for better reuse.
* hash.cxx (get_base_hash): Get the base from the session, or build it.
  (find_hash): Split into separate script/stapconf versions.
* cache.cxx (add_to_cache, get_from_cache): Ditto.
* main.cxx (main): Adapt caller, and delay stapconf until pass-4.
