Update documentation on this-command-keys to reflect new behavior

Browse Source 
* doc/lispref/commands.texi (Command Loop Info):
`this-command-keys' does not include the C-u any more, so remove
that from the description and the example
(bug#22107).

* src/keyboard.c (Fthis_single_command_keys): Don't say that
`this-command-keys' returns the C-u prefix (bug#22111).
