Fix debug help error message.

When given an invalid debug command, libguestfs responds with the
error message:

  libguestfs: error: debug: use 'debug help' to list the supported commands

However this command does not work, as debug requires two
arguments. This change updates the message to prompt the user to use
'debug help 0'.
