hosttools-tarball: Add openocd-legacy

Add openocd-legacy to the SDK, coexisting side-by-side with
a newer version of openocd. This was added as a safety backup
in order to guarantee previous openocd functionality.
This package can be removed from the SDK once the new openocd
functionality is confirmed.
