[yocto] [AB PATCH 22/22] yoctogit.py: sync on mv

[Elizabeth Flanagan]

From: Beth Flanagan <elizabeth.flanagan at intel.com>

On systems with very high load sometimes the system still thinks the
build dir is there. I've only seen this once, but a sync here ensures
that the system knows that build has been moved.
