Disable GSP Firmware for select instance families.

[larvacea]

Description of changes:

For some instance families in AWS, we wish to disable GSP firmware download in the NVIDIA kmod. We can do this by creating a configuration file in /etc/modprobe.d with the desired option, conditionally based on the instance family we fetch from IMDS. This must happen before we invoke driverdog to load the kmod. In bottlerocket, /etc is ephemeral, so we have to do this on each boot.

Testing done:

Manual testing demonstrates that the setting takes effect on the desired instance families, and does not take effect on other instance families. Tested on each kernel version, on aws-eks and aws-ecs variants.
