Followup to dbb9943
Despite skipping the `Smoke` check, it was observed on a *new* branch,
the `validate` task (specifically `git-validation`) will fail. This
is because:
* `$CIRRUS_LAST_GREEN_CHANGE` will be empty on a new branch.
* `$CIRRUS_BASE_SHA` is always empty for runs triggered by branch-push
* `$EPOCH_TEST_COMMIT` will be set to `YOU_FOUND_A_BUG`.
Fix this by eliminating the `Smoke` task entirely, simplifying all
the `make validate` operations into the `validate` cirrus task. Ensure
this task does not run when a new branch or tag is pushed.
Also, eliminate the `$CIRRUS_BUILD_ID` value as it's confusing and not
actually used anywhere. It was formerly used for building VM images,
but this has moved to another repo entirely.
