[PATCH] submodule: Improve handling of relative submodule URLs.

[Jacob Helwig <jacob.helwig@gmail.com>]

Relative URLs only worked with <proto>://<host>/<location> style URLs, and
would break when cloning a repository using <user>@<host>:<location> (scp)
style "URL"s.

When a submodule's URL was set to "../submodule.git", and the repository
using it was cloned from "git@example.com:repo.git", git would try to
clone the submodule from "git@example.com:repo.git/submodule.git", which
would not likely work.

This updates resolve_relative_url to handle the scp style URLs.
