roll_dep_test: remove file:// scheme in the git url

roll_dep_test is currently using file:///path/to/repo as git url.
Interestingly, the test is not failing in presubmit bot but
failing locally because it is trying to clone using sso protocol
(see: b/391455129#comment11). I think the presubmit bot is not
equipped with git-remote-sso so the tests are able to pass. However,
on a local workstation, git-remote-sso is available but it should
not be used as the file:// scheme should indicate using local
transport protocol. Quoted from
https://git-scm.com/docs/git-clone#_git_urls
> When Git doesn’t know how to handle a certain transport
protocol, it attempts to use the remote-<transport> remote helper,
if one exists.

Removing the file:// scheme appears to fix the issue even though
the only difference is the usage of --local flag according to the
doc.

fwiw, I did try to inject `--local` flag but it gives me a warning
`--local is ignored`. I haven't dig deep enough to figure out why
the flag is ignored.
