cmd/bent, benchmarks/copy: replace rsync exec's with sweet's copyDir
Turns out "cp -a" is not the same as rsync (if the target
already exists, is identical, but not writeable). This was
a problem for gomotes, and adding rsync to the gomote bundle
is a big hammer actually, so, do this instead.
This probably helps on Windows. Definitely won't hurt.
