cos_gpu_installer: add kernel module parameters as input flags

Flag --module-arg can be used to specify kernel module parameters for
GPU driver installer to use when loading NVIDIA GPU kernel modules.

It can be used to specify multiple kernel modules and their parameters.

For instance
```
./cos_gpu_installer -- --module-arg
nvidia.NVreg_EnableGpuFirmware=0 --module-arg
nvidia.NVreg_OpenRmEnableUnsupportedGpus=1 --module-arg
nvidia_uvm.uvm_debug_prints=1
```

cos_gpu_installer uses insmod to load kernel modules and can pass module
options to insmod:

```
insmod [ filename ] [ module options... ]
```

Tested:
1. Installed using module args listed in example
2. Used /sys/modules/<mod>/parameters to validate parameter values

BUG=b/277614899
