In #3310, the Dockerfile for the Tilt Velero container was modified to
call the `./hack/download-restic.sh` script. A side effect of this
change was that the context for the docker build was much larger as it
was the root of the Velero repo, rather than just the `_tiltbuild`
directory. With the frequent rebuilds of the image that happen when
using Tilt, a large amounts of disk space was being consumed by the
different layers of images builds in the Docker overlay filesystem (as
diffs could include the `.go` directory which can be several GBs).
This change modifies the `download-restic.sh` script to allow the output
directory for the restic binary to be configured. This means that the
script can be called directly from the Tiltfile and can be managed
outside the container build. This allows us to restore the previous
`_tiltbuild` context. It also speeds up image builds as we can download
restic once and use it for all builds rather than redownloading
frequently.
