git fetcher: make tag back to work, fix Yocto bug 972

In current git fetcher, tag does not work due to commit http://git.pokylinux.org/cgit/cgit.cgi/poky/commit/?id=5920e85c561624e657c126df58f5c378a8950bbc. Tag is not in sha256 form, so it will be treated invalid, and silently replaced by latest revision.

To fix it, this patch treat tag name as branches name, thus it will be handled correctly later. Thanks Richard for reviewing and proposing the better approach.

Fix [YOCTO #972]
