bitbake: fetch/git: make fewer calls to _contains_ref() from download()

Updating a local git repo clone currently results in multiple calls
to self._contains_ref(), some of which appear to be redundant and can
be eliminated by minor tweaks to the logic in download().

Also drop redundant calls to os.path.exists(ud.clonedir) before
self.need_update(), since need_update() includes its own built-in
check for the existance of ud.clonedir.
