create-pull-request: use git request-pull and arbitrary remotes
Allow for arbitrary remotes via a new -u argument. Remove the hard coded
references to the pokylinux repositories. Create the WEB_URL from known
remotes. Future patches can add additional WEB_URL mappings for remotes
like Git Hub, Gitorious, and kernel.org.
Rather than duplicating the git request-pull command ourselves, just use
the existing one.
