include/image.mk: introduce KERNEL_INITRAMFS_NAME variable

Browse source 
In case if we're interested in generation of non-binary images
(for example if we want images to be valid .elfs - and that's what we
want for ARC now) we have to instruct Device/Build/initramfs target to
use input file with some extension (in case of ARC it will be
essentially .elf).

Otherwise default binary vmlinux-initramfs (without extension) is used and
resulting images then are binaries instead of elfs.

Now having KERNEL_INITRAMFS_NAME variable it's possible to substitute
default $$(KERNEL_NAME)-initramfs with preferred option like
$$(KERNEL_NAME)-initramfs.elf.
