Adds support for passing target_os_only to the chromium recipe, and adds
"fetch ios" as an alias for passing both target_os=['ios'] and
target_os_only=True as described in the iOS build instructions page.

I figured out the issue right after asking (of course); I was missing the
chromium.py change that passed target_os_only through.

LGTM. Make sure you update the documentation to point at 'fetch ios' on both the
iOS page and the central UsingGit page. Thanks!

I'm getting "fatal: remote error: Git access forbidden" trying to push this. Do
I need special setup/access to commit to depot_tools?

depot_tools isn't a Git repo, so you probably need to set up git+svn and to 'git
cl dcommit' if that's not what you're doing now.
