[OE-core] [PATCH] kernel: introduce two convenient variables

[liu.ming50 at gmail.com]

From: Ming Liu <liu.ming50 at gmail.com>

Introduce KERNEL_INITRAMFS_BUNDLE_TYPES and KERNEL_INITRAMFS_FIT_TYPES
variables that a end user could override them easily in local.conf.

Drop the hard-coded initramfs image names, no functional changes.
