vsh: Fix '--help' option for virsh/virt-admin

The refactor of the libvirt tools command parser introduced a bug where
the '--help' option would cause an error:

 $ virsh list --help
 error: command 'list' doesn't support option --help

rather than printing the help for the command as the help option is
supposed to be handled separately from the real options.

Re-introduce the separate handling to the new parser code.
