    PR13353: use session parameters to search for build-id.
    
    Previous code used uname directly, which ignored the arch/machine
    data already available in the incoming systemtap_session instance.
    
    * session.h (native_build): New flag.
    * session.cxx (check_options): Compute it.
      (systemtap_session ctors): Heurstically estimate it.
    * setupdwfl.cxx (get_kernel_build_id): Use incoming kernel_build_tree
      to search for vmlinux.id.  If native build suspected, check
      /sys/kernel/notes.
