update(scripts/falco-driver-loader): minikube environment is now correctly detected

Browse Source 
If there is a file in `/etc/VERSION` the script assumes that it is running in a minikube
enviroment. Furthermore the logic in building the `KERNEL_VERSION` has been updated
according to how the kernel and probe modules are saved in the S3 bucket. The kernel version
for the minikube kernels includes also the minikube version.
