Drop libaio symlink step from CI workflows

Instant Client 19.10+ no longer requires libaio on Linux x86-64, so
the workaround for the Ubuntu 24.04 libaio.so.1t64 rename is
unnecessary once we install Instant Client from the zip archives
instead of the rpm (which historically pulled libaio in as an rpm
dependency).
