From: Christopher Larson <chris_larson@mentor.com>

When bitbake determines if a git clone needs updating, it only checks for the
needed srcrevs, not the revs listed in BB_GIT_SHALLOW_REVS, which will fail if
using shallow and the needed rev was added to the upstream git repo after a
previous fetch. Ensure that we also check for shallow revs.
