[yocto] [yocto-autobuilder][PATCH] yoctogit: add init to submodule update

[Stephano Cetola]

We replaced buildbot's standard copy function with our _srccopy
function when method=barecopy or movecopy. The srccopy will copy the
contents of the "source" directory into the build dir. We cannot
assume that submodules have not been added since the buildslave last
populated the source dir. Adding --init to the git submodule update
resolves this issue.
