yocto-bsp: Fix git url parsing, allowing for local mirrors

The git URLs used in bitbake recipes are not compatible directly with git.  In
bitbake-speak, all git URLs start with git:// and the protocol is optionally
specified in the SRC_URI. Local git mirrors are specified like so:

    git:///path/to/local/mirror.git;protocol=file

The URL that git requires would be:

    file:///path/to/local/mirror.git

Update the yocto-bsp kernel.py to make the necessary adjustment when parsing
the SRC_URI to extract the git URL.
