[OE-core] [PATCH] kernel.bbclass: Allow INITRAMFS_TASK to trigger copy initramfs code

[Jason Wessel]

Activating the INITRAMFS_TASK can cause circular dependencies, but
that is up to the end user to resolve in recipes.  The INITRAMFS_TASK
should also trigger immediate linking of the cpio task in the first
compile pass.  This was a subtle regression introduced by: 609d5a9ab
(kernel.bbclass, image.bbclass: Implement kernel INITRAMFS dependency
and bundling).

This patch restores the previous behavior and only affects the
INITRAMFS_TASK which is not set by any of the default build profiles
in oe-core.
