Update etc/update-copyright.py
This picks up some improvements from gcc/contrib. exceptions must derive from BaseException, port to python3, retain original file mode, fix name of script in examples. Adds libsframe to list of default dirs. I would have added gprofng too but there are some files claiming copyright by authors other than the Free Software Foundation.
