command_registration: add empty usage field to chained commands

Chained command require a subcommand as first argument. The usage
field for chained commands is not really important because the
"help" command will list all the subcommands with their respective
usage.

Add a empty usage field on all chained command.
The command "jlink config" can be either followed by a subcommand
or used alone, so use a dedicated usage string.
