Cirrus: Fix upload_release_archive on branch or tag
Cirrus-CI only sets `$CIRRUS_BASE_SHA` when testing PRs since the
destination and it's state is easy to discover.  However, when
post-merge and/or tag-push testing, the previous state is not
easily discoverable (changes have already merged).  The
`upload_release_archive` script incorrectly assumed this
variable was always set, causing a constant stream of post-merge
testing failures.

Tweak the `is_release()` function to properly handle an empty
`$CIRRUS_BASE_SHA` whether or not `$CIRRUS_TAG` is also set.  Also
update the unit-tests to check for this.  Also account for a
corner case where hack/get_ci_vm.sh is running on a VM w/o git.
