Fail fast if we cannot determine kubelet version (awslabs#1484)

kubelet is likely to fail when there is a mismatch with GLIBC that is in
the image vs the one golang uses to build the kubelet. So fail the image
right away when this happens as this specific kubelet binary will NOT work
in any instance started with this image.

2023-10-25T10:11:38-04:00:     amazon-ebs: kubelet: /lib64/libc.so.6: version `GLIBC_2.34' not found (required by kubelet)
