config-prepare: Initialize an empty KERNEL_DRIVERS_SKIP array unless it exists

Browse Source 
If the array exists in this location, initializing an empty array
will destroy all the data that was stored in it.
Do not initialize an empty KERNEL_DRIVERS_SKIP array if it exists.

This allows us to create an array anywhere in the script,
including the user configuration, in a secure way.
