veyron/services/mgmt/lib/binary: Fix cross-fs rename
DownloadToFile writes to a temporary file and then uses Rename when the
download is complete. By default, temp files are written to /tmp, which
is very often on a different filesystem, e.g. tmpfs.
This change puts the temporary file in the same directory as the final
filename.
