fix(@angular/cli): only add --version option on default command

The newly added `--version` option was previously added to all subcommands
which can result in a warning being shown if the subcommand was a builder
or schematics that also happened to have a `version` option. To support
the default `--version` option that displays the actual CLI version, the
option is now only added when no subcommand is present. This prevents
potential version option overlap.

(cherry picked from commit 83ef6a1)
