Return hash module values directly as strings

* session.h (systemtap_session): remove tracequery_path
* hash.cxx (find_tracequery_hash, find_typequery_hash): return strings
* tapsets.cxx (dwarf_cast_expanding_visitor::filter_special_modules):
  get the hashed path from the return value instead of a parameter
  (tracepoint_builder::init_dw): ditto, and don't stuff it in session
