clone: validate --origin option before use
Providing a bad origin name to `git clone` currently reports an
'invalid refspec' error instead of a more explicit message explaining
that the `--origin` option was malformed. This behavior dates back to
since 8434c2f1 (Build in clone, 2008-04-27). Reintroduce
validation for the provided `--origin` option, but notably _don't_
include a multi-level check (e.g. "foo/bar") that was present in the
original `git-clone.sh`. `git remote` allows multi-level remote names
since at least 46220ca100 (remote.c: Fix overtight refspec validation,
2008-03-20), so that appears to be the desired behavior.
