repo: make --version always work

We don't really care what the subcommand is set to when --version
output is requested, so stop enforcing it.  This fixes some weird
behavior like `repo --version version` fails, but `repo --version
help` works.

The new logic skips subcommand validation, so `repo --version asdf`
will still display the version output.  This matches git behavior,
and makes a bit of sense when we consider that the user really wants
to see the tool version, and probably doesn't care about anything
else on the command line.
