Update build scripts to use --mount instead of --volume to mount the host data into a container.

This is somewhat more verbose, but more readable and flexible. More importantly this is what docker documentation is recomending to use now.

Use the address of kSeed, rather than its value.

We initialize kSeed with &kSeed, so these are equivalent, but kSeed requires a
