[OE-core] [OE-Core][PATCH] image.bbclass: make kernel depmod data optional

[Dan McGregor]

From: Dan McGregor <dan.mcgregor at usask.ca>

This allows an image to skip the creation of kernel depmod
data. It is useful for creating an image that will run as a
container image inside a host with no knowledge of the parent's
kernel.
