api: generate_logo fix using the simpler logo on all Ubuntu versions

rather than using `package_latest_version` on `libicu-dev` which would be somewhat slow, check the binary of `libicudata.so` and see which version it is symlinked to

if the binary `libicudata.so` is not in the expected location, assume the version is lower than Unicode 13 and use the simpler logo
