[OE-core] [PATCH] kernel.bbclass: assign INITRAMFS_BASE_NAME using ?=

[Andre McCurdy]

Default values for KERNEL_IMAGE_BASE_NAME and MODULE_IMAGE_BASE_NAME
are already assigned using ?= and anyone wanting to over-ride one is
likely to want to over-ride them all. Make the three consistent with
each other.
