[erts,kernel,stdlib] fix escript/primary archive reloading
If the mtime of an escript/primary archive file changes after being
added to the code path, correctly reload the archive and update the
cache.
The existing code didn't consider that it might be a zip archive and failed:
=ERROR REPORT==== 3-Aug-2011::09:21:21 ===
File operation error: bad_central_directory. Target:
/escript_archive/module.beam. Function: get_file. Process: code_server.
Thanks David Reid and Hakan Mattson.
