update-test: tweak more edge cases.

Browse Source 
Don't try to `fetch --depth=1` unless we've confirmed the repository is
already shallow. Otherwise this can discard history from a full clone.

Additionally, if the repository wasn't shallow but there's no tags found
assume that Git is too old and try a naive sort if on Linux where `sort`
is able to sort versions.
