fix a couple of (system vm frame) accesses on boot errors

* libguile/backtrace.c (display_error_body): Don't look up the
  frame-source if Guile isn't initialized yet.  Fixes display-error
  before boot has finished.

* libguile/throw.c (handler_message): Likewise, don't backtrace before
  boot has finished, because we can't load (system vm frame).
