Add checkstatus command to the git fetcher

I'd like to use the fetcher's checkstatus method in the network sanity check of OpenEmbedded Core, to that end I've implemented the checkstatus method for the git fetcher using the ls-remote sub-command of git.

The following changes since commit 692c2fcead5c82249359ad54d2c7941d087a2eb3:

usermanual: The git fetcher defaults to the git protocol (or file) (2011-08-23 09:59:50 -0700)
