[autotest] Use rsync instead of cp in gs_offloader.
gsutil cp uses a lot of connections and has a big cpu overhead. Using
rsync instead allows
a) incremental uploads: If an upload failed, it doesn't need to be
re-started from scratch
b) faster uploads, because many files are sent over the same
connection.
BUG=None
DEPLOY=gs_offloader
TEST=Ran suites and tested with local results dir and testing bucket.
