Fix handling of changed prefix keys in tutorial

Browse source 
* lisp/tutorial.el (tutorial--find-changed-keys): Use keymapp to
detect prefix definitions rather than hard-coding them.  A notable
omission from the hard-coded list was mode-specific-command-prefix,
whose subcommands are often rebound (bug#40725).
