this allows us to maintain the bazel build files until they're removed,
but tries to avoid accidentally encouraging their use
`make update-all` implementes a non-bazel version of
`hack/update-all.sh`, with `hack/update-all.sh` now calling make but
also doing the bazel stuff it used to.

This slightly modifies our existing helm chart verification script to
accept the location of a tarball containing the chart we're verifying.
That in turn allows us to more generally use the script for both
validating the chart we build using make and the chart we build using
bazel.

The existing comparison fails due to the 'nounset' option being on.
That failure masks the nicely formatted error message the if message is
trying to print. This correctly prints the intended error instead of
bash's default unset behavior.
